I, myself, am not really a big forum poster..  Especially in a photography forum since I concider myself a newbie when it comes to photography.. 

I do however browse the forums alot to learn new things, but it's as you say, they feel quite empty unfortunately..

I guess people are different.. Personally I'm quite shy.. I feel that if I don't have anything worthwhile to contribute on a subject then I'd rather not post just to "increase my post count" so to speak.. I realise that's not really helping much here tho :P

CRITIC, n. A person who boasts himself hard to
please because nobody tries to please him.
