Hiya
In March, according to our web log analyser we had 15654 unique visitors. To date (3 AM on the 12th) we have had 5177 unique visitors. This doesn't count crawlers such as Googlebot.
I didn't bother to cut over Postnuke's analysis from TMC 1. However, you can find Postnuke's stats for since TMC 2 went live
here - not that I set much store by them. We're not downing in web crawlers the way we were, but there's still a huge volume of bot traffic (almost all of it Google - the other search engines tend to leave us alone more or less).
Initial signs are that the investment in time in setting up the Google sitemap has been worth it.
Cheers
