An expert on what? Resurrecting old threads or spouting bollocks? The great thing about the interweb is that it attracts all sorts of idiocy and armchair theorists and you clearly fit into the former and probably the latter too. No matter, they usually get ignored and/or bored fairly rapidly and disappear up their own self-righteous chuff spouting something along the lines of 'It was never like that in MY day,' or 'When I was in we did this and that and it was brilliant.'
Enjoy the site, you'll find some illuminating characters on it, some of whom know a damn sight more than you do and are ever so slightly more stylish about it too.
