I've recently been stumbling around StumbleUpon.
If you haven't seen this site before, and you've got a few minutes to spare, it's a great way to browse the internet. Tell it what you are interested in and click on stumble. The more sites you tell it you 'like' the more it will come up with to suit your interests. It's really very clever!
.... if you're not careful though, you may find that a few hours have vanished without you noticing!
I'm here >> http://www.stumbleupon.com/stumbler/dizzyizzyhndmde/ if you'd like to see what I've been stumbling across.
