While the so-called old media has been slow to pick up on our recent news item about student-entrepreneur Benjamin Roodman's cool mobile social networking service (ImThere), the blogosphere is all over it. Which should come as no surprise, since it involves techie gadgety and connects Internet and cell phone technology. That's the sort of thing bloggers jump on. The mainstream media? Not so much, apparently. Or not as quickly. We think they're missing out on a great story. ImThere could be the next YouTube.

Here's a roundup of blog coverage from the past couple of days:

• A MySpace for the mobile generation, from Smart Mobs, the blog of Virtual Community author Howard Rheingold.

• Tracking friends around music venues, from Wired's blog for music fans, Listening Post.

• Missouri student goes mobile..., from Textually.org.

• One of Ypulse's two mobile social networks to watch. We think it's really the only one to watch, but we admit a slight bias.
