I sometimes get the same feeling reading these forums
Not nearly as often because its well regulated and largely lacking in malice, but the sheer level of banality astounds me sometimes. But then, I suppose it's not exactly meant to be revelatory stuff now is it?
Speaking from personal experience people get bored and write whatever pops into their minds. Most don't think what they're saying is especially important, that status is usually ascribed to it by others who either agree or take exception. I once commented on a song, lamenting how none of my friends liked it. it was a throwaway comment that I didn't expect to hear about ever again, but some dipshit took that as my believing I was better than my friends and, by extension, everyone else. I meant no such thing, but people just seem to like getting pissed off about nothing.
I agree, they are pointless, but what's the point in anything like that? What's the point in these forums? What do they accomplish, except to swallow up valuable time? Truth is, most things involving commenting on the web are pointless, but, if you just have to write whatever pops into your head, its better than being self-absorbed enough to register a twitter account.
Or maybe this is just me being bored and chatting shit online, God knows we all do it.
