I know that there are a lot of sock puppets in the list, but how to determine who is a sockpuppet and who not?

^^ Exactly why the list isn't longer. How do you know who is a sock-puppet and who isn't? Still, I hope your chat room idea is beneficial and I totally understand the investors want and need different things than the "bloggers". For the "Real" ones, it would be great to hear their direct feedback.
