I do use voice chat, but only with a few people since I'm kinda shy and well, talking to compelete strangers that says "Add me on skype" isnt really my thing..
But a voice chat in Runescape... I don't know, it feels like that would make things less secure, since anyone can talk to anyone, which might make it easier to break rules (solicitation).. And it would probably cause a lot of lagging and stuff, but yeah...
