IMHO:
This is an enjoyable group, but it is not the beginning of a sacred document that will influence civilization for a millenium. It is an internet forum, and if it becomes troublesome in any fashion, as it has a couple of times in the past, DR may choose to shut it down. Which is a reasonable decision: we are guests on DR's website, and should try to avoid embarassing him, and anticipate consequences if we do so.
Regarding credibility, I most appreciate those posts that offer references and footnotes, along with opinions and anecdotes.

And Blast may actually be a 14 year old girl in dubuque, and I may be cop in illinois trolling for internet abusers. It doesn't matter: If the advice is good, it doesn't matter who offers it. I recently read biographies of several of my favorite philosophers: all of them wrote influential and powerful treatises: none of them were good company. YMMV.
