Me on the internet
Most popular social network in Russia, I use it mainly for communications and chatting.
Russian IT blogging portal. I don’t often write there, but sometimes do.
World-known Q&A site for programmers, where I’ve asked quite a lot of questions. Also, same account on other StackExchange sites.
Code hosting for any projects. I used to keep my code with Mercurial and Git there.
Code hosting for open-source projects. I used to keep my code with Git there.
Emails (still work): firstname.lastname@example.org, email@example.com, firstname.lastname@example.org. Nickname “chersanya” on many other sites is mine too.
Plain old Email communication. Actually, you can send your mail to any address which ends with @plav.in.
