He's also linked to some interesting Pittsburgh blogs (including this one), so I too will point out a few:
Bike Pittsburgh covers anything that relates to biking in Pittsburgh (including national developments)
Pittsburghers Gretchen and Frank (both students, I think) give an interesting take on "The Blurgh" with occasional references to how it has changed since their parents' youth. (NOTE: It's set in a fictional future in which Pittsburgh is a better place.)
ClickNathan has his say about Pittsburgh issues and random other topics, like digital photography.
Green Is Good, based in Pittsburgh, looks at green energy here and elsewhere.
My Homewood reveals (among other things) that I could buy a house in Homewood (Pittsburgh's 13th Ward) for less than the new laptop will cost. Or I could go wild and spend $3700 for a different house. Um, I guess it's all "location, location, location." They look like pretty normal houses to me, not made out of Tinkertoys or covered in tarpaper.
Nullspace also notes the housing prices in Homewood.
Pop City focuses on technology, sustainability, development, and arts and culture here.
Pittsblog, by a local law professor, looks at a variety of local matters including an upcoming talk on intellectual property that sounds worth checking out.
Tube City Almanac's server wasn't working but maybe you can get through and find out what they offer...
Walking Pittsburgh explores different parts of the city and provides photos and history.
That's it for Pittsburgh blogs on Brent's list, but let's not forget Kristen's Procrastinating in Pittsburgh, and Tazza d'Oro, my neighborhood cafe, has its own blog. Tazza d'Oro is one of Pittsburgh's several (many?) special cafes. Unlike the cafes I haunt near school, it has a clientele of all ages and is an object of passionate devotion within the neighborhood. You can find knitting groups, writing groups, bicyclists, political organizers, students, mothers with small children, theater people, and entrepreneurs, and (in the warm weather, outdoors) dogs there. And now the big question: after I try (again) to order the new laptop, should I set off in the snow to Tazza, stay home, or go to the library?
