Kind of like a 43Things...<p>I didn't want to start off with a criticism, but last thing I want to do is create an account anywhere before I'm sold on the concept. I like to look around, but these walled-garden type apps make that difficult to do. So I rarely sign up.<p>You should be able to get some use out of an application (such as this) even from a logged out perspective. As an example, Last.FM lets you browse and view a lot without logging in. I can find similar artists, read bios etc...<p>If I could see peoples goals, and sort of explore the site first, it might be a bit more compelling...
