Having the option to videochat with anyone, even if you don't really know them.
Doing groups chats for hours with friends or people for fun.
I would do it because I think it would ne interesting :)

I wouldn't because of the nature of the site.
1. Advice site. Some people coming for help, often suffering mental illness or extreme emotional conditions. Presence of highly volatile individuals could ruin the experience.
2. Trust & Anonymity. Many people come here sharing deeply personal issues. They can do this because they are anonymous and do not need to worry about negative reprocussions for sharing. Video chat would erode that to some extent.
I do support the presence of a chat-like functionality for the purpose of talking about a question or problem with someone, but I don't think video information is necessary to do that.1
