Marco isn't the only pro to have been on here. A few other pros, if national or continental level have been here. Forget the names, but they've chimed in.
Lance is known to be a web geek, and likes reading about himself, and refers to those who don't swallow his stories whole as "trolls", so I'm sure he's peeked in here on several occasions. Whether he's actually registered and posted, that's another question.
I was going to say the same thing. I think he had no idea how knowledgeable some fans here are and hardcore this place is, and ended up a little shell shocked when he left.
Since no racers are really going to come in here and talk about doping and such, it might be nice if we could get some ex-racers and ex-support no longer in the sport to do similar.
