I'm from there originally, and I agree, but the weather really is a problem. It's terrible. I live in Portland now, an area renowned for its gray rainy days and lack of sunlight. And yet, it has been 50º-60º and sunny for nearly a month now. Whenever I check Pittsburgh it's hovering around 0º. It's really a shame because I love Pittsburgh.
I was kind of looking for that too. Cost of living in this area is pretty low and the tech scene is growing. The only downside is you have to live in Pittsburgh and I actually like sunshine so I've been thinking of moving.
Our city isn't that bad! Though it does rain a good deal, and is cloudy a lot.
That said there are a lot of amenities (museums, shows, groups, &c) and things-to-do, so we're not as isolated and dull as a lot of people I've met feel we are.
I live in Ohio but work in Squirrel Hill. The city has transformed over the years and is a really nice place. The only downside is the weather. This time of year it's easier to complain about weather but we literally get some of the lowest amount of direct sunlight in the country. We basically have 2 seasons: 4 months of summer, 8 months of winter/grey. Other than that the area is ok. Where I live it's pretty depressing old industry towns with nothing left, but like I said I don't live in Pittsburgh.
