Neighborhood blogs seem to be a web-based vanguard of the meatspace phenomenon of young, affluent, tech-hip people who are populating the once industrial-decayed parts of Brooklyn. Seems to be a sort of mild spinoff of Gothamist, same idea, but more localized. Examples:
Ditmas Park Blog
The Gowanus Lounge
These are just the ones I've actually browsed; each has links to more.
The times are-a-changin'.
