Codeforces users with high rating are more engaged in community life
By pani.natalia, history, 5 weeks ago, In English

People tend to act according to patterns. Those who have already invested a lot of effort into Codeforces continue participating in contests. And every time I take another visualization course, I choose Codeforces data for practice:-)
.
If you are fond of details, here is the numbers

These statuses are returned by API and that's why numbers are different from Rating page which shows users who participated in contests during the last 6 months.

  • Vote: I like it
  • +79
  • Vote: I do not like it

Maybe because the total user number is low if rating is high?

Would this mean that ratings are inflated? New users join, participate in a few contests, do poorly, which increases the performance of everyone else, then quit. 24/7.

    New users always get positive delta in the first couple of contests.

    And that rating is gotten from higher rated users.

    So, the rating system is not inflated

    Well, you actually didn't say anything wrong there but I suggest you to avoid saying "please upvote". That's kinda irritating, people will upvote if they find it useful so no use saying that.

    But I still want to know why you allways use capital letters in each words. This makes people feel truly uncomfortable.

    Sorry, I didn't see that in the last "my" word, you didn't use capital letters :)

      What is the point of losing contribution because some grammar error?

    As Grammar, you spelt grammar incorrectly

Maybe if a person is active,it will often gain its rating?

Nice blog! A question, which users you considered as retired* ones, based on table columns I suppose its those who haven't been online last month? If so I think retired is not really appropriate naming for that

The statistics show that we often just toss out any ratings before retiring. (xd)

I've found the mentioned public APIs.

As a mobile developer, I'm looking to create something useful with them in the near future once I come up with a good idea. Do you have any suggestions?
