A friend pointed me toward Rabble, a product from Intercasting Corp, itself founded by three ex-MP3.com execs. Rabble is an application for cell phones and similar handheld devices that is integrated with popular blogging applications. "Sort of like myspace, but for your telephone," he says. It's also got some integrated local search capabilities to give you access to nearby blogs.

The target market is the ever-popular 14- to 25-year olds, for whom cell phones are a far more integrated social device than they are for older cell users.
