What's a good source to find hot products?

What are some good websites to find out what products everyone is searching for online? Right now the only two I can think of are Amazon's hourly rankings and Ebay's pulse. Those are nice, but they aren't comprehensive enough - everything in the top 100 is the typical saturated junk like ipods, iphones, etc.

Any ideas?

If you find some ebay powersellers and put in their usernames at goofbay.com then you can see what they are selling, and that should give you an idea. Another new gadgets, etc. site is gizmodo.com which shows you what's hot or coming out in technology (new phones, ipods, tv's, radios, etc)
