It looks like a nice piece of software.

I tried it with facebook and it reported a change everytime it connected. There is no doubt that if I analyze the structure of the facebook page and find exactly the places where a change is of interest to me, then I may be able to configure it. But it would be nice if Dejal Simon could do it automatically: what I'm interested in are the things you don't get notified by facebook:
• somebody writes on the wall of a group of your choice
• there are new members in a group of your choice
The developer told me there will be a plug-in for facebook, I hope it will do this.
