At Michael's insistence, I'm going to try to put together a large list of terms and definitions relevant to SEO, web development and the Internet in general. The formats will look like (as Dan suggested):

Cloak·ing
n.
1. Something only bad people do
2. Something only smart people do
3. The only way to keep "them" from seeing your super-optimized META tags
4. Something Google does because people in Brazil get the Brazilian version when they type in www.google.com

We'll also have a nifty little delivery system ala Google suggest (since they're relatively easy to build). The only part we need help with is the list of terms... Want to contribute (and have your name and site on the list)? Just drop ideas in the comments below - you can just leave a list of terms and we'll research the possible meanings and format them. We'll also include a suggestor tool so you can add to the dictionary once it's live.
