Codeforces: Statistics 2015
By MikeMirzayanov, history, 9 years ago, translation, In English

Hello!

Here are some statistics about 2015. I'm glad to see our growth. Frankly, each year I'm afraid to see that we stop to grow, but each year I see 20-50% growth! Thank you for your interest :-)

In addition, I have written before about progress in the development and championships and rounds with partner companies in 2015. If you have not read, please read.

Here are the funny pictures with the statistics:


Growth of registerations. This year we overcame 300K users!




Counted only participated in rated events in period July-December.
Previous year I included TopCoder statistics here, but now it is even
somehow uncomfortable because of 5534 topcoder active users.





You become more and more active! Keep up the good work!





All blog posts, having at least +5 votes, having at least +20 votes.

    Yeah, fake accounts is something TC really doesn't have to worry about.

      why? isn't there sufficient participants? or, people are too honest there? PS: I'm not so familiar with tc

it would be great if you add the chart of the number of contest that users participate (how many users participated in 1,2,3... contests)

I still regret that I didn't decide to join CF earlier.
Anyway I'm not afraid of its future, great job and keep doing your job, Mike ;)

I'm curious about shitposting statistics: (number of downvotes) as a function of (number of users).

Theory says that the growth is exponential — for example, there's Descartes law of imageboards

Any community that gets its laughs by pretending to be idiots will eventually be flooded by actual idiots who think they're in good company.

Congratulations. What is the reason for fewer comments in 2012 and 2013?

I've recently counted distribution of number of players per ELO rank, think it's interesting too: image

    Hmm, that's weird, I did the same (and ELO per countries also) and I have a kind of pick around 1750.

      I have discretization in 100 points of ELO. You have precise scheme.

All these graphs will be forced to have much more smaller scales if this growth continues for other 2-4 years xD

300,000 of us? Like a small country. A perfect time to declare independence, but from who?

i believe that a quarter of more than 300.000 accounts are clone accounts.
