Campus Buzz Hubs

TechCrunch: BuzzHubb is best summarized as bringing the utility of next-gen Yahoo Groups to the mobile college student, but done in a creative, lightweight manner. The first fundamental element of BuzzHubb is that it establishes boundaries around the university campus – you can only join a school’s BuzzHubb community if you are part of the school (a great concept that Facebook championed). Once you have joined, you can join existing Hubbs, or quickly establish your own.
College students have complex, sometimes overlapping social group relationships. BuzzHubb makes communicating with those groups simple and engaging. A Hubb is a group of individuals who can share group messages quickly and easily from their phone, the web, or their social network. There are several types of Hubbs: Broadcast Hubbs, where you join, but there is a single author (e.g, the campus sports blog), Invitation-only Hubbs, where an existing member needs to invite you to join (a study group, a team, a special interest group) and all can contribute, and Open Hubbs, where anyone on campus can join and contribute (e.g., Obama 2008).
