I'm mainly editing OpenStreetMap now, once I was active in polish news service LinuxNews.pl and I still do some things on polish Wikipedia. With Krzysztof Lichota we did localized version of Ubuntu (Ubuntu/Kubuntu PL 6.06).

Ubuntu is my desktop choice after years of using Mandriva, because it really does make desktop Linux nice, clean and usable place, while reusing the most reliable and widest FLOSS platform available (Debian) and attracting new people to collaborate.

"Ubuntu on desktop, Debian at heart". ;-}
