#18 The Social butterfly.

I have been on twitter Me :) for about 4 years or so now.  I seem to take it in spells.  I think it would be a great way to make class announcements and to keep an eye on the pulse of your students.  As a matter of fact so many of these great programs and sites would be quite useful.  However, there simply are not enough hours in the day to keep up with all of them.  I think perhaps starting with one, and then building as you become accustom to using it and keeping it updated is perhaps the best plan of action.
