Mike Torres has a nice post up explaining the new Spaces statistics page:
With some changes to the way Spaces statistics work, you may be wondering "what happened to the ability to see the search terms people used to find my space?" Don’t fret, you can still do this even though it doesn’t show up with the referring address (we don’t show URL parameters there.)
Pesonally, I found the old one much more useful.
But I gotta say, I’m loving the new templates the Spaces team has provided. Now if they would only resolve my number one Spaces request . . .
