GenderAnalyzer is a site that allows you to plug in any URL and get an informed, nearly instant, opinion as to whether that site is probably written mostly by a man or mostly by a woman.
Fun, yes! Accurate, no!
A few I tried:
Dlisted is the rabid-pet project of Michael K, but GenderAnalyzer claims:
"We have strong indicators that http://www.dlisted.blogspot.com is written by a woman (99%)."
KennethInThe212 is the personal site of Kenneth Walsh, so manly he has facial hair. Though:
"We think http://www.kennethinthe212.com is written by a woman (78%)."
Pam's House Blend is the well known site of Pam Spaulding, or is it ghost-written by Michael Ayers:
"We think http://www.pamshouseblend.com/ is written by a man (71%)."
Just Jared is written by Mr. Jared Eng, yet:
"We think http://justjared.buzznet.com/ is written by a woman (63%)."
Joe.My.God. is done by he-man Joe Jervis mostly in first-person, but the site can only muster a shot in the dark:
"We guess http://www.joemygod.blogspot.com is written by a man (54%), however it's quite gender neutral."
Hilariously, Perez Hilton can't even be guessed at thanks to his poor grammar and typos:
"Sorry, we can only classify web pages written in English."
Most insanely, my own site must have a huge set of hairy balls, go-figuratively speaking:
"We have strong indicators that http://www.boyculture.typepad.com is written by a man (95%)."
Interesting tidbits: People and Us were both pegged as written by dudes, with an identical 61% chance; CNN was pegged as very womanly at 89% while Fox News butched it up and was called 73% male. DailyKos (founded by a man, written by both genders) was a very masc 84%, but HuffingtonPost, founded by a woman, written by both genders out-testosteroned it at 95%.
Sites it got more right? Towleroad (66%), AndrewSullivan (76%) and DrudgeReport (85%).
