Not to butt in, but as a Pittsburgher I can comment on living here. Here are some thoughts, in no particular order:
1.) Incredibly affordable/cheap to live here. I shared a whole house for <$350/mo for three years. I am scared to move to another city because I have been so spoiled here. At the same time, ready to move .
2.) Pgh gets a bad rap, but does have great amenities no matter what your interests are. Great opportunities for sports (watching and playing), art, theater, museums, etc. And Pitt's Cathedral of Learning is probably one of the coolest buildings in the world.
3.) My one main complaint is that the city isn't as progressive as others...but it's trying.
4.) We have some great parks/green space here...if you're into that kind of thing.
5.) Lots of young, educated types...again, if you're into that kinda thing.
6.) Finally, Pittsburghese (the native language) is fun both to learn and experience.
