What is Digg?63 Comments
- topcat31, on 07/03/2008, -3/+92Digg also has this line in the algorithm:
if(submission=xkcd) then position = frontpage + snarky comments about how it always gets there - Pillage, on 07/03/2008, -0/+43Isn't Reddit open source? How much "exposing" did he have to do?
- pingpants, on 07/03/2008, -2/+45if the algorithm's taking into account the digger's geo location why are there so many popular submissions from new jersey
- DarthDaddy, on 07/03/2008, -5/+43** Visual Basic Syntax **
If Digg.Submitter = "MrBabyMan" Then
blnFrontPage = True
Else
MsgBox "Haha Sucker, better luck next time!"
blnFrontPage = False
End If - hoodmonkey, on 07/03/2008, -1/+16if(perferredLanguage == "VB"){
careerStatus = "toilet";
} - menwuur, on 07/03/2008, -3/+13i lol'ed
- nreynolds, on 07/03/2008, -1/+10not in VB. I learned to program in java with = and == and it's WAY better than VB's = and =...
- greeniemeani, on 07/03/2008, -0/+8I honestly wasn't expecting any logarithms...
- PullingTeeth, on 07/03/2008, -2/+11K. Rose will be pleased
- hakz, on 07/03/2008, -1/+8funny how everything BUT digg is exposed
- theutopian, on 07/03/2008, -1/+7It doesn't say that in the title.... buried as retarded.
- adidos, on 07/03/2008, -2/+8and VB sucks...
- HillerMylife, on 07/24/2008, -1/+7The StumbleUpon algorithm is more complicated than any math class I've ever taken.
- paintist, on 07/03/2008, -0/+5I wonder if he'll have to change his own suspected digg algorithm now that his own story became popular.
- zadadka, on 07/03/2008, -0/+5Eh?
Al Gore what? - twiztidsinz, on 07/03/2008, -4/+8Wow.... All that just to bash digg at the end?
- seanieb, on 07/03/2008, -0/+4I think he has gotten the Digg algorithm wrong, some of those "factors" clearly don't have any effect.
- greeniemeani, on 07/03/2008, -0/+3What the hell language has an "IN" construct?
- hakz, on 07/03/2008, -0/+3what???
- andreshb, on 07/03/2008, -1/+4As I understood from Peter Norvig from Google Research - with a large data set, the simpler the algorithm can be - in other words, its all about the data set so I would not be surprised that if someone reverse-engineers the algorithm (up to that point) of Digg, it would be rather simple.
More info on algorithms and data sets:

- inactive, on 07/03/2008, -0/+3Rhythm.
- cowsgonemadd3, on 07/03/2008, -0/+2For 5 minutes somebody might know the algorithm then it gets posted on the site they are trying to beat so all can see and then it gets changed. Genius!
- Rojahon, on 07/03/2008, -0/+2No, the time B is constant to that specific time they listed.
- sfrench, on 07/03/2008, -0/+2Large data sets make outliers in your data set contribute less overall, and reduce spikes. Think about the two following averaging exercises and how the one outlier (1000) affects the overall result based on the sample size and how the average really relates to representing the true nature of the series being averaged.
Avg of 1 2 3 1000 = 1006/4 = 251.5
Avg of 1, 2, 3, ... , 98, 99, 100, 1000 = 6050/101 = 59.9 - fattehboi, on 07/03/2008, -0/+2its back up.
digg is more than just a 10,000 pound gorilla - badjoke, on 07/04/2008, -0/+2That's the page title...not the article title.
CNN - Man breaks out of jail != CNN Man breaks out of jail! - Rojahon, on 07/03/2008, -0/+2FTA: 45000 is the amount of seconds in 12.5 hours. This constant is used in combination with yts to "water down" votes as they are made farther and farther from the time the article was submitted.
As near as I can tell, y*ts / 45000 has nothing to do with the number of votes that are recieved, assuming that the balance doesn't switch between up and down votes. It doesn't "water down" votes at all. It just provides a way of putting newer and positively voted articles above older articles. Although, somewhat strangely, it puts newer, negatively voted articles below older, negatively voted articles.
To be honest, that algorithm seems kind of strange to me. The number of votes is essentially meaningless, and becomes more meaningless as time passes from that fixed date of December 8th, 2005. Why they even bother taking the log is beyond me. The magnitude of y*ts /45000 given 3 years since that date will be over 2000, while the log(10000) -- that's counting 10000 votes -- is only 4... - Canute, on 07/03/2008, -0/+2It sure is. http://code.reddit.com/
- lordewoks, on 07/03/2008, -0/+2lets not forget XKCD, huffingtonpost and divinecaroline
- theutopian, on 07/04/2008, -0/+2Sigh... apparently the retardation is contagious. Since you're incapable of scrolling up and reading. I paste the title here for you.
"Reddit, Stumbleupon, Del.icio.us ... Algorithms Exposed!"
Do you see Digg there? No. That's what I thought. - shondell, on 07/03/2008, -2/+4I'm pretty sure Digg's algorithm can't be explained period.
- Lolosway, on 07/03/2008, -0/+2Really amazed to see the digger's geographical location along with a few other factors taken into consideration as a possibility. With all the additional variables considered I am curious now as to how each adds their own effect into the equation and at what percent; or if its just speculation as the sources for digg were not included.
- lancehomer, on 08/18/2008, -0/+1"Although, somewhat strangely, it puts newer, negatively voted articles below older, negatively voted articles." I've come to the same conclusion about this equation and therefore question how accurate it really is.
- tigerglebe, on 07/03/2008, -0/+1Digg has a lot of gaming going on but at least you get a chance to hit the frontpage if unknown. On Fark you don't hit the frontpage unless you are a paid Total Fark. Period.
- billbugger, on 07/03/2008, -0/+1it works
- zadadka, on 07/03/2008, -0/+1Pah!
Sounds like a no-hoper jazz quartet.....
;) - Inquisition, on 07/04/2008, -0/+1Personally, I think that the "Submitter's authority" and "Submitter's friends and fans" should be discarded altogether. That would put a stop once and for all the gaming that still happens on Digg. I haven't seen many babyman submissions that I enjoyed that weren't already on Reddit, and I don't see why something should make the front page because the submitter has spent waaaaay too much time adding friends to his list that aren't really interested in what they post,and probably don't take too much time trying to figure out how to keep this guy from shouting every new submission to them.
Then, I think about the tantrum that the "Digg elites" (as they call themselves) threw when Digg announced the change in the algorithm. They boycotted for about a day before they came back and figured out that they could still game Digg. They don't game Reddit or fark simply because the algorithms are simple, and transparent. it is a lot harder to game a simple system, because there are less variables that can be exploited. Don't believeme? I dare the "Digg elite" to try to become Reddit elite. - inactive, on 07/22/2008, -0/+1I don`t know much about algorithms but the same guys always drive stories to the homepage, that is not gaming , its simply because they have a lot of mutuals and fans that will digg and share their story, pretty much legal if we consider Digg`s TOS. Otherwise they wouldn`t have implemented the shouting feature from the start, agree? Now add me to your friend list if you really want to share interesting stories and drive them to the homepage.. ;)
- mlbwebdesign, on 07/03/2008, -0/+1How long did they take to figure it out tho?
$count++; - zman14321, on 07/04/2008, -0/+1I'm pretty sure reddit is now open source.
- FearMoth, on 07/04/2008, -0/+1greeniemeani: Pascal?
if i in [1..100] then ... - jpaul6, on 07/03/2008, -1/+2Is it just me, or does the reddit algorithm make no sense at all - the (verbal) description seems to indicate a per-voter score, which is absent from the actual mathematical description
- sharanyan, on 03/30/2009, -0/+1Social networking sites allow you the opportunity to reach out to thousands even millions of people across the globe. You can interact by blogging, e mailing, swapping pictures, chatting etc. There are plenty of forums that give you a platform to voice your opinion. No matter if you do not want to put up something, you can simply read what is there and update your knowledge on that subject.
http://www.social-media-optimizations.com - TheDeepFriar, on 07/03/2008, -1/+2Digg Effect.............mirror anyone?
- arjie, on 07/04/2008, -1/+2Yeesh, I'm an idiot. Yeah, it's written right there, I thought it was some miscellaneous info and left it out.
Dugg you up, thanks. - spud311, on 07/04/2008, -0/+1I think that while the formula might be good for a few tips on tightening up your profile and posts / content. Unless you can get 500 users to Digg an item - there is not much value.
- ddover, on 07/03/2008, -0/+1Nope, I still think it applies.
