I tried out Wridea today, which is supposed to be a web application for tracking ideas. It's a pretty slick interface, but once you start playing around with it you realize that it has a lot of limitations. There's very little in the way of tutorials or ideas for ways to use it. Then, when you check the corporate blog, which hasn't been updated in six months, you start to get the sense that it's not exactly a booming community. For me, the dumbest thing is that you can add categories to your notes, but not search for them. What's the point of that? You can't even pull up a list of ideas with the same category. The outdated blog promises these capabilities in a future release, but I wouldn't hold your breath.
