That piece linked to a post by Chris Bowers on MYDD that cited Booman Tribune as a new Scoop site. I went there and saw European Tribune on the front page, clicked, and found myself here. The idea of a left-leaning European community blog felt spot-on to me, and I signed up immediately. ET had been officially up for two days.
I was reading dkos and most of all Billmon's site where I also dared to comment for the first time. That's were I met Jérôme and later also on dKos and Booman, so it was no question to sign up with ET when he announced it.
In those two days, more than 500 people signed up before I did.
