I confess that I am not a great fan of Twitter. For me things have to have a purpose, and to date I do not have a reason to use Twitter. Perhaps it is my antisocial nature. Or that I tend not to work in a network that required this kind of rapid connection. But for those of you who do, there is a reminder service that utilises it. If you know the Twitter system, you will be very familiar with its use. Now just add reminders! This could be for groups of for individuals.
