MSN Beta Search, I love it!
 

Particularly because I rank first page for a lot of my keywords - Hopefully they don't change their algo before they launch :)

They probably will :)

They probably will too.. Their SERPs are a mess.

Actually, they aren't - they're the complete opposite of a mess.

The results produced are much more relevant than google. Google gives so many crap irrelevant results

I think it's crap.

It seems as though, from my limited perspective and experience, that they are placing much more emphasis on on-page optimization which might be why I'm doing well. My site is structured in xhtml/css and I paid close attention to those other on-page factors.

I only have 23 backlinks (many of which are still unaccounted for, only 4 are currently showing in the backlinks of yahoo), and although I have made sure to pay close attention to my anchor text - I'm clearly beating sites who have 100's of backlinks.

Or perhaps the terms I'm shooting for just aren't all that competitive, although I do know "fitness plans" is at least somewhat competitive, and I'm #5.
