I really like the user pages, so much so that I would like to re-direct my domain to it.
I presume any referring traffic is welcome.
But right underneath that graph is this huge empty space which is being used for nothing. How about a facebook style wall there, so that any conversation members or clients want to have can be held there and then tweeted as well. Would generate more marketing tweets - more traffic and isn't as hardcore trader style as tweeting just trades. Then the conversation could be tweeted as well.
And there isn't huge empty void there....
