I have a suggestion more for user convenience than anything.
I know on Ustream.com, you can "fave" other users and keep them on your profile for easy access. When they are live is displayed so you don't have to search to see who is broadcasting and who isn't. I thought that would be more effective than saving other users in an internet browser's favorites or bookmarks. Maybe the livestream staff could think about putting that in when they upgrade the website next time; because I know that was one of my favorite aspects of Ustream before I switched here.
