..good to see that digg's motives are still genuine. they simply want to make the user experience better. - ilikediggalots, on 06/30/2008, -11/+182Hmmm, very social, very intresting, very well done video, very promising, and very DUGG! Keep it up digg team.
- Awspire, on 06/30/2008, -9/+128Digg Recommendation Engine...
http://i31.tinypic.com/vpudt1.jpg - YesImAChick, on 06/30/2008, -10/+117Great job Anton!
- Uncle_Joe, on 06/30/2008, -19/+113That's some epic ***** right there.
- tbeseda, on 06/30/2008, -10/+101Stay out of my head Charles!
- inactive, on 06/30/2008, -10/+85Anton you are the man, thanks for developing the maths and algo for this recommendation engine. Thanks to all the digg developers and rest of the crew for working hard. Great job guys, keep up the great work.
- sockpuppets, on 06/30/2008, -4/+68I've suddenly started receiving a lot of stories about donkeys in miniskirts. Should I be concerned?
- geneticlone, on 06/30/2008, -2/+51I can finally meet my soul mate, yay.
- joestump, on 06/30/2008, -5/+47I can't stress how absolutely awesome Anton Kast is. He's brilliant, hilarious, curious and unique. It's truly a pleasure working alongside him. If you get a chance to say hello to Anton at a Digg Meetup take it and be prepared to laugh and learn.
Great job Anton! - Matt2k, on 06/30/2008, -1/+41He's more like a "fungineer" than a scientist
- techblogLAT, on 06/30/2008, -3/+44The founder of Digg isn't a super user?
- bluegene, on 06/30/2008, -3/+43Wow...Digg is becoming a Google of Social News
- inactive, on 06/30/2008, -3/+41*how well
- Conwaysb0718, on 06/30/2008, -4/+40Ha, i wonder how many users are going to be recommended only babyman and saleem submissions.
- inactive, on 06/30/2008, -0/+28True but at least you can block them if you do.
- misterpony, on 06/30/2008, -2/+25This should be the biggest thing to happen with Digg since the switch from v2 to v3. This could really change the entire way people use the site. Bringing Digg back to web 2.0 hip.
- NJank, on 06/30/2008, -0/+23that depends. there are some donkeys that really shouldn't wear miniskirts.
- Thomaschaaf, on 06/30/2008, -3/+23I bet MrBabyMan will get this feature before I do :/
- Simon83, on 06/30/2008, -11/+31Very curious to see how good this works
- joestump, on 06/30/2008, -0/+19It doesn't recommend users. It shows you the users who are recommending the stories. It shows an entire list of stories and says "Users X, Y and Z recommended these stories". You can then block people from the Recommendation Engine if the stories popping up don't suit your tastes.
Also, it only recommends stories in topics you've recently Dugg stories in. In other words, if you haven't Dugg a story in Golf in the last 30 days it won't recommend stories from Golf. - Kev585, on 06/30/2008, -12/+31Was never excited for this, but having seen what it might be, I can't wait
- inactive, on 06/30/2008, -0/+17Your bloodline has to go all the way back to mrbabyman. Once you're in the beta, you can never leave.
- sockpuppets, on 06/30/2008, -5/+20The new 4chan accelerator rolling out this week!
- lordtyros, on 06/30/2008, -6/+20Good job. Hopefully it doesn't turn into an underused piece of crap like Digg Labs.
- da5idblacksun, on 06/30/2008, -5/+19Killer feature - much needed.
- dbldn, on 06/30/2008, -2/+15Wait... are there other users than saleem & babyman?!
- webresources, on 06/30/2008, -3/+15digg is getting better. Great.
And it would be perfect if users would be able to play with it. Like find users with interest to Ajax & jQuery. - thaistick, on 07/01/2008, -0/+11i have a theory on people that type a long theory on people that claim to be first.
- richbradshaw, on 06/30/2008, -0/+11I'd guess he designs recommendation engines, or something.
- Angostura, on 06/30/2008, -0/+11I'm actually looking forward to this as a way to block their trash.
- baramunchies, on 06/30/2008, -8/+18who is this kevin rose?
- dbldn, on 06/30/2008, -3/+13Sadly no. Kevin is an amazingly smart guy with the vision to see and do what most others can't. But his vision is being tarnished by a bunch of web-celebrity seekers that step on others and their hard work for the front page of digg. So instead of having thousands of users picking the best stories we have 17 people telling people what they should voting for.
- Gesiwuj, on 06/30/2008, -1/+11I think it recommends stories based on what similar users (who dugg similar things to you) are digging.
- AngryAngryBrian, on 06/30/2008, -10/+20I have a theory on people who always try to get "First". What it really comes back to is kindergarten. A persons worth was based on their position in line. The first person in line got to pick the cool table at lunch and was the first to the slide. No one wanted to be at the end of the line, and those with friends could move to the center of the line by cutting, but the weak, slow, or unpopular had to get in the back and hope that another student where just as slow and as unpopular as them. Those who where forced to follow became jealous of the front of the line, but they were second class citizens, the weakest of the herd. They ate last, they played last, and they even went to the bathroom last. The internet puts everyone on the same level and where the slow and the unpopular once had no grounds to move to the front, they take it. This brings some minor satisfaction for all the times they where picked last, and for getting the greasy scrapped remains of the hotdog surprise at lunch. Users who try their hardest to get the first post are just striving for attention, trying to make up their lack of humor, whit, and knowledge with a careless, but quick submit button.
Nah, just kidding, its space radiation. - dn11, on 06/30/2008, -0/+9But Charles is in charge of your wrongs and your rights.... I want Charles in charge of me.
- dn11, on 06/30/2008, -3/+11"lead scientist" is an odd job title to me. He apparently has a Ph.D in physics, but I'm trying to figure out how that qualifies him to design social networks. Regardless, I'm sure he's probably the smartest person at digg. I'm just surprised they didn't put a lab coat on him with a microscope and test tubes in this video.
- Thrilltone, on 06/30/2008, -2/+10Digg's method of popularizing stories blows.
Add a bunch of random friends and then pester the ***** out of them.
Yuck. Why hand power to your most annoying *****? - ChrisWalkr, on 06/30/2008, -0/+7Revision3 don't host their own videos, a company called BitGravity does.
- sfrench, on 06/30/2008, -0/+7Donkeys.... Depends.... there is definitely a joke here I should stay away from.
- BetterOffEd, on 06/30/2008, -0/+6I like it, but oh-so-strategically placed quotation marks would've helped your joke a little bit here.
- rivalius13, on 06/30/2008, -0/+6No, but we are BFFs!
- seanieb, on 06/30/2008, -1/+7"Prior to Digg, Kast was the Chief Architect at Light Crafts and a senior software engineer at Network Physics, Inc. He has an A.B. Physics from the University of Chicago (1989) and a Ph.D. in Physics from U.C. Berkeley (1995)."
- geneticlone, on 06/30/2008, -0/+6789/Hylia/Hyrule
- Downwritemad, on 06/30/2008, -1/+7I love the title Lead Scientist. I don't know what he does but it's science and you can't argue with that.
- seanieb, on 06/30/2008, -2/+8Graph database...do tell us more. Sounds cool.
Oh and I love that ye gave us the logic and thinking behind the entire thing, not only does it keep things open and transparent, It keeps us tuned in. Thanks. - Diggnabbit, on 06/30/2008, -1/+7Hmm... so, this could be sort of a double-edged sword, couldn't it? If it does a good job of getting stories/users to you that are similar to what you've dug already, that seems like a good thing.
But, will it make it less likely that you'll see new things or stuff that you would not have otherwise found? That's why I come to Digg: to be exposed to new stuff, not just to be confirmed in what I already like. - sprash, on 06/30/2008, -1/+6Well the math is pretty basic stuff (correlation coefficients woohoo...) and not really advanced. The greater challenge might have been server performance and scalability. I guess you will have some kind of super matrix with (Number of Digg users)^2 entries with all the coefficients in it. That means for every new Digg user you have to create a new row with (Number of Digg users) + 1 entries.
So lets say you have about 3000000 Digg users and one matrix for each subtopic which are about 50 and you store all entries in 32-bit float numbers you get 1.44 * 10 ^16 Bits to store. That are about 1800 Terabytes where you have recalculate 3000000 32-bit floats = 96 MB every time somebody makes a digg... not bad!
well.. this cant be true... - tmaiden, on 06/30/2008, -1/+6The Recommendation Engine is coming soon!
During this initial launch phase, the Recommendation Engine is being offered to a random sampling of Diggers. Please check back soon to see if you are one of the lucky few. In the meantime, check out the original Upcoming section filled with the most recent stories just submitted on Digg. Thanks for your patience.
