Pindax is similar to Wallwisher, one of my favorite Web 2.0 applications.

You can put virtual Post-It Notes on a “board,” and include multimedia links. Pindax seems to have more features than Wallwisher, though. Of course, when you add features, you add complexity, which is why I think I’ll still be sticking with Wallwisher. But Pindax is still worth a look.

Thanks for Tami Brass for the tip.
