Meebo
So I set up my Meebo account. My name is Ian_Not_Robbins_Son. You have to work at Orinda to get the joke. So I can see why Meebo would be a valuable tool for individuals working at a variety of different companies and organizations as it let’s you share a common product regardless of your company’s individual message service provider.
Here at our library I guess it would be a useful way for staff at the circ. or ref. desks to call for back up, particularly when their busy assisting patrons. But for the that to work people would have to log on to meebo everyday, which might take a little effort.
