One of the Knight News Challenge projects (the $5 million yearly contest to fund innovative digital news delivery ideas), ReportingOn, has launched in public beta.

ReportingOn’s Ryan Sholin describes the service:

ReportingOn.com will be a simple way for journalists to update their peers on the stories they’re working on right now. Tag your 140-character-or-less updates with the beat you’re on, and find peers reporting on similar beats to make connections, introduce yourself to potential mentors, or discover an unsung hero.

You can follow the ReportingOn project’s progress on the microblogging service Twitter and on the ReportingOn blog.
