Stickam

Stickam is a social networking website devoted to live-streaming video (aka video chatting/ web shows).

That is stickam's primary focus. However, if you create a profile on stickam, you can also add your pictures, videos, and audio to your profile. I should mention that stickam is completely free and add supported. You don't have to be registered on the site to use it. Although the privacy settings may keep you from viewing people's live video chats if you're not a registered user.
Like most other social networking websites, you can add friends, send your friends messages, or send friend requests to people who aren't currently in your friends list. Unlike most social networking websites, the focus is on social networking through live video chatting. Whether that be private person-to-person chatting, group chatting, or public chatting. You can see who out of your friends are currently online, and who is currently "live" and you can "block", "ban", or "kick" someone for any reason. You can make people you like "moderators" to help you control your live chat rooms.
It's a fun model for a social networking site and I enjoy using it quite a bit. Most of the people on the site use it at least once a week judging from whom I've come across on the site.
