I live in Old City, Philly, where we have Indy Hall. (<a href="http://indyhall.com/" rel="nofollow">http://indyhall.com/</a>) A lot of people like it, but I really don't want to work around people who, plus or minus, are just like me. (I believe the word for us is "nerds.")<p>My favorite co-working space is a coffee shop because it tends to be a lot more diverse than the intentionally created spaces I've seen. That said, I think I would very much enjoy working out of Paragraph, a writing space in Manhattan. (<a href="http://www.paragraphny.com/" rel="nofollow">http://www.paragraphny.com/</a>)
