In all honesty, Social Catcher is quite a superb service. The idea is ace: the application looks at all the conversations that you have with your friends on the Social Web, and based on what has been said it provides a list of shopping suggestions that you are sure to like.
We all reveal a lot about ourselves when talking to others on Facebook and Twitter, and these are the two main services that Social Catcher takes into account. And note that if you are a blogger, you can actually submit its RSS feed and have that analyzed as well.
While I am the first to admit that the implementation is not faultless, the site is interesting like little else. Sure, it can come up with things that have nothing to do with what you want or need, for the simple reason that not everything you mention on Facebook and Twitter reflects a personal interest (you might be talking about something a friend is keen on, for example). But just give Social Catcher time to become fully-developed.
