Hello:
In the spirit of teaching my fellow cellar dwellers how to fish, I offer:
http://www.stumbleupon.com
A Firefox extension that does exactly what this thread does. From their page:
"StumbleUpon is an intelligent browsing tool for sharing and discovering great websites. As you click Stumble!, you'll get high-quality pages matched to your personal preferences. These pages have been explicitly recommended (rated I like it) by friends and other SU members with similar interests. Rating these sites shares them with your friends and peers – you will automatically 'stumble upon' each others favorites sites."
I have used it extensively and can say that in terms of variety, there is no higher quality source for internet time-sinks than StumbleUpon. I urge caution when installing it and using it. Perhaps some safety line is a good idea, like connecting the power supply of the computer to an automatic shut off switch. Set it for, say, dinnertime, to avoid going hungry.
Stumble On!
