This thing is the business - if you have your own blog then go to this link and paste in your url -

It has a guess as to whether your blog is written by a bloke or a girl! Apparently, mine was 70 per cent man. Probably not that tough a guess though, given all the fighting, shooting and drinking references.
Kinda convoluted, but I found this blog through an old post you'd written on Thorntree about getting a visa to Myanmar as a journalist. I'm sad to report that my photoblog was considered 77% written by a man (yes, seven percent manlier than you), and my travelogues 64% written by a man. Don't know what it's based on, considering my frequent notes of the special treatment, flirting, and harassment I get as a woman traveling solo. Also, my name is the link. Funny concept, the analyzer.
