As a grease monkey script its pretty awesome, runs exactly how it should an does how it should. I wish I got this script when the annoying fan pages first came out on face book an they where everywhere.
The site has a great idea in where you can see the fan pages without even having to do the scungie inviting all your friends and stuff and if pages haven't been added you can submit them an there normally heaps quick in adding them
The only con now is that the fan pages fad has died down, which makes the script not anywhere near as useful as it used to be :(, still on the occasion it works good. But makes me wonder where its going to go from now
