It's hard to say, but a conservative figure of 'real human' uniques per day is around 500 (Taken from Tribal Fusion).
I can't believe how rumors are spread from thin air.. about the reasons why Jon and his partner backed out, etc. Everybody seems to be an expert...
For those interested, I posted the site up for sale again yesterday and I revised my description (Can be viewed at DP:
Large Established Movie Review Site For Sale) which gives more information, including that on traffic, etc.
I don't blame Jon and his partner for backing out at the last minute - they didn't exactly back out, just offered a lower price - but it should be noted I was never 'hiding' anything about the traffic or anything. On the contrary I was always completely up front stating that Urchin stats were highly inflated with search bots. The confusion came in with just how inflated (guesstimate is real traffic is around 20% of Urchin stats).
