I have insane posting rate, and I am the top forum poster.
Top forum poster in regard to quantity right? I was always raised with the concept of "quality over quantity."
Not making the statement that your forum postings lack quality but maybe your sales pitch could be more effective if you promoted your signature space as an area associated with someone who is known, respected, and active in the Bitcoin forum/community. Again not saying you aren't any of those just that your sales pitch, in my opinion, equates to "I write a lot of posts" and I'm sure you contribute more than just "a lot of posts."
