This just cracks me up... One of my best performing blogs which has been in position 1 for 2 keywords for over a year and page one for 5 others suddenly disappeared... beyond 500 places!

 Been that way for about 2 weeks.

Checked it today and it is back with a vengeance... funny thing though, now my site has position 1-3 for the same keyword???

I thought the new algorithm was supposed to eliminate this. Not much variety for the Google customer... 

But then... who's complaining ;-)
