That is the great thing and the worst thing about the Internet. Anyone can present themselves as an expert - all voices or posts carry equal weight. It is up to the reader to determine the legitimate and the bogus. No button on the site is going to show who the experts are. I've seen people who have 3,000+ posts, lots of green chicklets and have only one snake. That person may not have actual experience, but they may have spent a lot of time learning, so their voice could be just as valid as Brian or Kevin's on a particular topic. The other curse of the Internet age is that people want knowledge handed to them exactly as they want it, with no work involved. Learning requires work. Things that come cheaply with out work are not valued very much.
