When there's nothing going on with the stock, I see nothing wrong with occasionally posting friendly, chatty, or funny posts. If there comes a time when these types of posts are so prevalent that they prevent the DD from being talked about, or they take over the conversation and replace talking about the stock....then I'd agree they are a problem. But now, the way it's been, I see no problems.

The chat (or whatever you want to call it) room is filled with people, not DD robots. Ignore the posts/people you don't want to hear from if it bothers you that much.
