Well, it might be influenced by other boards I actively participate in, but my policy is to stick to a few threads that cover the topic, and only start a new thread when the discussion is straying too far away from the initial topic. While here, it seems like every single new strain of thought or different angle on the same topic merits a new thread. Sometimes it ends up being a good move, but most of the times it's just the same old discussion all over again, with the same arguments made by the same people. And unfortunately this is especially the case with everything concerning doping and/or Lance Armstrong. As long as this Twitter-like thread starting doesn't change, every other thread will be choked imo.
Sorry for hijacking the thread btw

I wouldn't know about how much percent of the peloton uses PED's, but I think it all depends on what your definition of a PED is. I think there's a thin line and a whole grey area of semantics and arbitrary rules that make up the rules of what is considered doping, and what not. Every rider will be 'doped' to some extent, but some manage to stay within the accepted borders, while others cross them without being so much more jacked than others. A 'clean' peloton is impossible per definition imo, and not only in cycling.
