webcams are for fags/geeks/weirdos, tak, did no one tell you?
There's a button for video, but i don't see a point in owning a webcam let alone using one, so can't say i've tried it 
webcam and voice chat come under my list of "stupid lame ass features/gimmicks", don't see the need for either of them when the novelty wears off after about 2 seconds.
Maybe if your some l33t businessman and need a satellite hookup with Mr Yamachuci in some elaborate presentation to demonstrate why daz whites aren't much cleaner than than persil whites?
or am i being overly skeptical?
edit:
same goes for the whiteboard feature, which is mildly more fun than the aforementioned gimmicks
