Unfortunately some regular posters don't have any patterns to there postings. If I think of anymore I'll be sure to post em.
What kind of patterns are you looking for?
When I think of "regular posters" I think about people who offer comments on a wide range of topics which naturally produces a wide range a work which probably makes patterns hard to distinguish. It's certainly not like everyone who posts often is always going to be talking about the same one or two things.
