A friend of mine -- Steven Berlin Johnson -- just launched outside.in. I think it's a cool concept -- worth checking out and reading about it in his blog. He's attempting to create a single place that unites all the hyperlocal content on the web. I know a bit of the challenges that await him....I'm looking forward to touching base, drinking beer, and talking about the web and local content. Until then, my advice to him is to focus on creating the definitive guide to park slope neighborhood and nail that (period) (before trying to scale).
