We'd like to start this week's run-down by wishing a very happy birthday to parent blog Gothamist, which turned four on Friday. If it wasn't for them, the rest of us wouldn't be here. They celebrated their birthday by nabbing an interview with star Adrian Grenier, who misses NYC public transportation when he's working in LA. They also reported on NYU students protesting a band whose name is also known as a slur, the new graffiti king in town, Bill Cosby's adorable dog, and the disturbing tale of a yoga instructor who was found guilty of killing his girlfriend, a dancer from Ohio who stripped to make ends meet.

Bostonist is grateful that the Celtics broke their losing streak on Valentine's Day—perhaps the players girlfriends were withholding the slam dunk until they won! They were also all about Valentine's Day: they made sausage, taught breaking up 2.0, and shopped for Barbie Dolls that were suspiciously like the ones in San Francisco.

Torontoist wasn't sure how they felt about four Greenpeace activists chaining themselves together in the offices of Kleenex's manufacturer. They hunted down the remains of Microsoft's Windows Vista Ice House, and wondered about the future of their men's magazines after the death of one.

Phillyist got pretty into local politics this week, what with their wacky local mayoral race and being Facebooked by city council candidates. They also stumbled across some sweet vintage concert footage and, in honor of Valentine's Day, listed ten things to love about Philly.
