The email from WordPress contains hype such as:
"Your Annual Report from WordPress.com"... "Your 2011 in blogging"... "Our stats helper monkeys have been busy putting together a personalized report detailing how your blog did in 2011!"
I'm guessing that everybody who's using Jetpack will have received such an email.
Indeed, a quick Google shows that several folk are including details from their reports in their blogs.
Hopefully those folk will have checked the supplied facts and figures - I'd find it hard to believe that I'm the only user to discover that his report is a crock of 5h1t.
Here's a clickable edited copy of the report prepared for me:
FWIW, my editing is based on the same data that was (and still is) available to those WordPress/Jetpack monkeys.
Happy New Year!
