I don't read every post by every member, and most of the time lately I don't even open more than 5 or 6 threads on any given day, not unless I have a project I'm REALLY procrastinating on, so if I'm wrong about the sincerity thing, oh well - my impression may not be based on the same experience you may have had, but even this illustrates my point -

which is - oh nevermind. Weelittledrummer has the best post on the subject. Good post, wld.
