At the Twitter Conference, I met with Nate Heinrich. He is co-founder of Flaggpole, a location-based service for Twitter. Flaggpole lets people use Twitter to connect on a local or neighborhood level.

Visit flaggpole.com or follow them on Twitter at @flaggpole.

Talked to Eric Peterson and Jeff Katz, a couple of the folks from Twitalyzer, a Twitter analytics tool.

In a sea of tools for gauging your Twitter accounts effectiveness, what sets their's apart is that you get advice on how to improve the different metrics.
