Is this a Google Dance in 2008?

Yes, right now Google is showing some really different search results for many popular keyword searches. To me, it looks like Google is hosting a party for many old time keyword friends and url relatives.

I see many #6 Google result penalties going back to number 1 for their respected keywords and I'm also seeing many old timers dropping a little to leave room for other old timers that used to share that keyword in the top 10...
