Saturday morning, when the metro Atlanta area was reeling from one tornado and bracing for several more, a community of local Atlanta videobloggers was using the microblogging service Twitter to communicate with one another about where things were happening and who was covering them.

iReporter SpaceyG messaged that she'd heard damage was severe in Vine City, a neighborhood south of downtown Atlanta, and that news crews hadn't yet arrived. Shelbinator, another iReport contributor, heard the message and headed over, camera in hand. His video reports from Vine City were some of the first we saw from that neighborhood, which was so hard hit city authorities warned people who don't need to go there to stay out.

This weekend's example makes me wonder: could there be a way for iReporters in the same area, or who are affected by the same kinds of events, to get in touch with one another? Head over to the comments for a brainstorm?
