Read a post the other day on how noone posts idea's anymore. I think I thought of a pretty good idea for sig whores and whatnot
Here's the idea
Search Engine Sigs
ok everyone go run and register searchenginesigs.com
Here's the idea
You're sig calls a script, the script is a bot that scans the page for keyword relevancy, you have a list of keywords you're looking for, the keyword with the highest relevency then displays your sig code image to that keyword.

Now you're saying... but sig codes can't change, well true, you'd have to setup a image script to call the banner, and then the link would redirect to that site
