Hi, are you associated with the Plus Buddy site? There are two typos on the frontpage: "... and provides recommmendations of who to follow..." and "We'll recommned Google+ users ...".
Thanks for catching this. We're on it. How do you find the tool working?
I don't have a Facebook account and I'm not on Google+, so I can't really evaluate the tool from a personal perspective. But I find it weird, that I get some recommendations if I click the "recommend" button without entering any URL at all or complete garbage. You could add some form of input validation to see if users entered a valid Facebook URL. If a user enters his Facebook URL in a wrong way, he will get some results, but these recommendations are not based on his profile.
