45 minutes ago I received my first ever StumbleUpon recommendations email. I'm not sure if these has been sent out before, but I have to say, I love it!
I'm a huge Stumble fan, Especially if the system decided to send a whole bunch of traffic my way. Through SU I have discovered a whole lot of new, fun sites, which have enriched my life in many ways. New information, new fun and new knowledge that is hard to find if you just type in a search in Google.
The more precise you are in targeting your interest, the faster the system will learn what you actually like. The sites served to you when you click on the Stumble button are getting better and better the more you Stumble.
