It's a mark of social-networking penetration: Twitter is now being used by a customer of prostitutes to track his hired-sex conquests. Even the most seasoned search-engine marketing fool would have to doff his douchey hat to "Sexhobbyist," who's paying girls for the privilege of juggling their affections — and blogging about it. Sexhobbyist's business goal? Besides doing it for the mere thrill, it's possible he's hoping to subsidize his "hobby" by driving traffic to the AdultFriendFinder ads on his blog. There's just one hole in his business plan: Does he not date women who use the Internet? Forget his "sorta girlfriend" finding him out. His whoremongering is sprinkled with links to escort review boards — just the places the dancers he's getting with are likely to read. Maybe they'd be flattered by the attention, which we hope they knew they were getting, even semi-anonymously; he mentions the names of the cities and clubs he visits. It would be easy for the girls to trace his travels via Twitter, compare notes, and bust him. Guys, take this as a how-not-to — connecting the dots of your sex life for no more reward than a few clicks.
