Google puts (much of) CampusActivism.org in the Supplemental Results

Ouch! My website traffic is down by 50-70%. Now I'm getting around 1200-1500 visits/day. Google has put many of this site's pages in the supplemental results, which means they appear very low in the search engine rankings and will generally get you zero google search traffic.

I could understand Google putting the school pages or silly zip codes pages in supplementals - but they put many of the group pages in supplementals. That doesn't make sense because those pages have a lot of unique content (group descriptions and names differ a lot).

It's possible that having both the activismnetwork.org and campusactivism.org site with the same content is causing trouble. I think it's more likely that Google is constantly expanding its definition of what "duplicate content" is. What's strange is that I was able to get my findradio.us site out of supplementals - and that site has a lot less incoming links.
