SPIN,
Review the TOU's that I linked in an earlier post. My interpretation says such a topic is OK, however I recommend we do not discuss the topic (of what should stay, what should be removed) on the board itself. Read the TOU's and keep your posts well within their bounds. If you believe a post remains that should be removed, report the TOU violation. If you believe a post has been removed that adhered to the TOU's, either PM Matt of take it up with him on his Q&A board (be sure to reply to one of his posts so it toggles his mailbox).
And, above all, keep the posts targeted to the firm, the stock, the competitive environment, and the investment.
