Some statistics: who are we?
By MikeMirzayanov, 15 years ago, translation, In English

This post contains few words and many pictures. I decided to publish statistics on Codeforces visitors for the past two months. Why? I believe that it might be interesting. I took pictures from Google Analitycs.

Codeforces was born little more than 4 months ago. During this time, we held 16 contests (though one of them was non-rated). There are more than 4000 registered users, and every day we get about 30 more. There are 1797 coders participated in the contests, many of them participate in our contests regularly. The average number of registrations for one competition is growing, and I want to believe that soon it will conquer psychological barrier 1000 users. Also codeforces social network is popular: more than 400 posts, almost 6000 comments. The leader of the hit parade of posts is this post, has collected to date 184 comments. Bravo, SkidanovAlex! And of course I say thank you to everyone who helped make the project: those who help in the development, who make the problems, translate texts and write the alternative solutions, participate in community life, and just take part in contests. Thank you!

Below you will find a few more pictures and statistics, the total traffic of about 250KB.

Hmm if you can, please add which os people are using.
Also like spoj and topcoder is you give a page for statistics about the average rating of a country,school and also country wise rank list of participants ; it could become very interesting ;)

Can anyone please tell me where I can find the blogs of other users? codeforces.ru only contains the official announcements, and "Recent actions" doesn't contain all the blog feeds.

    The only way, known to me, is to find the user, and then press " Blog entries" link in his profile page.

    You can also search for tags you're interested in, for instance http://codeforces.net/search?query=tutorial

    Seems that "tag search" is hidden now because of one issue.
    Hope it will be improved and returned back later.

    The other way known to me is Brute force:
     - get the link of this blogpost (for example, I have that - http://codeforces.net/blog/entry/427)
     - instead of 427 enter the natural numbers from 1 to 453 (453 - the number of last blogpost for this moment).

    Yep, it's difficult and you get lot's of blogposts only-in-russian, but this is the way.
