I have the opposite reaction. When a stock I'm interested in doesn't have a thread already created here (or has one with few replies) I like it even more. If you want to invest in the Apples and General Motors of the world you'll never have a shortage of people to discuss your ideas with.
But I thought this board is for contrarian-value investors. I read stuff on seeking-alpha and feel the way you do, the more popular it is, the more I won't invest in it. But if this board is really like that then maybe I should find another forum?
Ironic, Eh!
I remember a board member data mined the investment ideas section. Came to conclusion that the ideas that have less replies tend to outperform.
