Don't dream it, be it.
Curriculum Vitæ at LinkedIn
Сurriculum vitæ (or résumé). Appropriate to use for professional contacts.
Microblog at Twitter
Microblog generally in English. I’m certain that bots and automatic tweets update it much more often than I do personally.
Scrobbled Music at Last.fm
Music listening history since 2006. If the term “scrobbling” sounds confusing, the Wikipedia might help.
Bookmarks at Pinboard
A pile of web bookmarks accumulated since 2006. First at del.isio.us, now at Pinboard. Perhaps, the most entertaining are with the “fun” tag.
Tips and Lists at Foursquare
Before the schism it used to be about check-ins, badges and mayorships. Now it’s about tips and expertise. Still useless, but still enthralling.
Games at Steam
Oh, well. Perhaps, I have too many games still being unplayed.
User Page at Wikipedia
Most of contributions go to the Russian language edition of Wikipedia (see also the global contributions page). The topic is mainly European Union.
Blog at LiveJournal
Personal blog in English and Russian. One of the oldest informational pollution I introduced into the Internet starting far back in 2003. Tried to post at least once per year lately but failed.
Photos at Instagram
Mostly post various artefacts and peculiarities, rarely in real time. Annoyed when users post more than once per day.
Profile at Facebook
Overvalued time killer. Good to keep in touch and organise events, but I prefer good old e-mails.
Photos at Flickr
Photos I took and bothered to publish. Thousands of unpublished photos collect dust on my hard drive.
Videos at Vimeo
None of my videos published there. Just reserved the username.
