Google Madness

Google has gone nuts! There is no other way of explaining it. NUTS!!! MAD!! PR always varies, but search results are usually quite stable. However the latest 'google dance' and update has changed all that. Rankings for pages have dropped completely. Why? Supposedly they were trying to stop spammers. Well that failed! Searching for 'insurance ireland' or 'irish insurance' is unlikely to produce any usable results. I won't even start on the ones related to our sector... It's just maddening. Who is gaining?
