1. Rebtel lets you call abroad on-the-go for cheap or free (if you are located in one of the ‘Rebtel countries’), bypassing the need to use your computer. Since I call out-of-country quite frequently, this is incredibly useful. I haven’t paid a cent to Rebtel; the international part of the call had always been free to me. I haven’t fully broken up with Skype though.
2. Muxtape is so simple, but maybe that’s the appeal. It has one of the cleanest and simplest interface I’ve ever seen. You can’t download your mixtapes, but it’s still an easy way to quickly share your mixes online.
3. Surf the Channel sure has a lot of channels. I don’t download TV shows (really!), so I go here sometimes to watch missed episodes.
4. Pixish is new. I haven’t really tried it, but it seems like a good idea for freelancers!
5. Common ties is also new. If you’re a freelance writer or designer, it may be good to check out. But Postsecret is still my first love.

I know my list is severely lacking/incomplete. Rather than stealing someone else’s list to put on here and call it my own, I’ll just link you to someone else’s list directly. I know, how annoying of me. Here’s CNN Money/Business’s Web 2.0 list.
