I started on Twitter in March 2009. I never would have thought this to happen, but I've gained a remarkable amount of followers since. Thank You. In fact, with almost 50,000 followers, I'm actually one of the most followed Finns on Twitter. So I want to give something back. My 50,000th follower will get a physical Bitcoin coin worth 1 BTC, made by Casascius . But rewarding my latest follower and ignoring all the rest wouldn't be fair. So, I'll give another 1 BTC coin to a random follower. The winners will also get a copy of Thomas Rid's new book Cyber War Will Not Take Place . Rules and conditions: I select who wins. No complaints. Winners get the coins and books via mail.
