Study Stickies Facebook Application

I have been working on the Study Stickies Facebook app, which may be of interest to people here.

Study Stickies allows you to take notes (stickies) from printed books and online resources (e.g., pdf/html documents, videos, etc.). You can easily retrieve important information later and (optionally) share your knowledge with others.

The program is quite stable and has already been accepted into the Facebook application directory.

Any feedback would be appreciated.
