What are some websites that are unusual, creative, and entertaining/helpful?

Usually when someone asks me that question I say “Fluther.com”

but lately the prize for creativity goes to “Green Porno” for me. http://www.sundancechannel.com/greenporno

theres a site where you dont click on anything, you just move your mouse and hold it. i cant think of the url now

Well, of course, I think Fluther is pretty remarkable. I’d suggest going to the Webby Awards page and browsing those winners. I also subscribe to StumbleUpon and find the most amazing sites.

I agree with chatnoir. StumbleUpon has been awesome for finding new sites. I think http://zefrank.com is unusual, creative, and entertaining. But, helpful? That depends on the help you need.

What was the site you found?
