we would like to have some kind of system to allow users to vote for
useful posts, and to show which users are more active in the forums.
Why? Are your readers that stupid? Have you bought into the thought that newbies have to be protected? Do you think that "you" have the answer and others have to be protected from being enticed by the dark lord?
Anybody who reads the boards will soon figure out who posts frequently and there are certainly enough naysayers around here, no matter what your investing philosophy is, to give anybody with two brain cells feedback whatever. And certainly enough different approaches that give some people apoplexy. That is their problem. You are going down the my way or the highway path.
Why do we need big brother? This is the outgrowth of a paternalistic belief in your own infallability People who can't read or comprehend shouldn't be managing their own investments. The market and investing is as darwinian as real life. Would you use a programmer b/c he was a nice guy or could talk a good game? You have programmers who are good at slog work and programmers who make jumps; do you only want the sloggers?
