Recently, I was a speaker at a conference in Bratislava, Slovakia, called Daily Web. Everybody there was super-connected. Everyone was on both Facebook and Twitter. While I was at the conference, I received invites from my fellow attendees get connected on Twitter, Facebook and even LinkedIn.
During a break, I was told that there are about 60,000 Slovakian users of Facebook, using a mix of the available Czech interface and the English. They were all much newer to Twitter, but the conference did have a Twitter profile and I chose to create the hash tag for the conference, #dailywebsk. I was told Facebook is beginning to bogart the populations of local Slovakian communities and there are plans to localize Facebook into Slovakian the way that it is localized in the Czech Republic and Germany.
