Sorry Doug,
I didn't want to appear to be on the attack, I spend lots of time on our sites making sure we are #1 in Sussex, with the odd site popping up using this system, which do seem to drop off after a while.
Each to their own, we are all doing the same thing, making a living. There is a lot of speculation as to Google's preferences, none of which seem to have a great deal of fact attached, if total relevance is really their mantra, then I think we may see some changes.
Regards
S
