I'm just curious, because I know you have been working on the referrers part of the stats. OK - 22 hours, but I'm about to go to bed!
I have blogsurfer showing up but that is the only one. I do not think I have ever had no referrers since I started, although I don't remember back 12 months exactly.
No Facebook, no other blogs, no WordPress of any sort (i.e. forums, Dashboard or anything), no email referrers even.
I don't see anyone else posting about it, so it may be a regional thing, perhaps?
Plenty of search terms, that is not a problem - just no referrers.
The blog I need help with is teamoyeniyi.com.
