I very much agree with you first and last paragraphs, but disagree just as strongly with the second. The likes of Tony, Larry Goddard and many others are far better modellers than I ever can (or want to) be. I don't think that they call themselves experts, it is a status which is thrust upon them by others who seek their advice and follow their modelling. There are many such on here, even more elsewhere. I have seen no criticism, except constructive when asked for.
Comments like yours will lead (and have lead) to these people stopping posting or, worse, deleting threads (you know who you are!). Please don't be negative.
