Top 100 tools for Twittering Teachers

Having tried and tested Twitter a couple of years ago I am almost becoming the anti-twitter spokesperson with the amount of dribble being circulated on it of late from the corporate world and wannabe celebrities.  But I am not naive to the potential and actual success people have had from using it regularly to create and strengthen their profile and social networks. ie: Barack Obama.  I  also accept it is a great classroom tool specifically in the secondary school area  and I came across this article from bestcollegesonline.com that lists the top 100 twitter tools for teachers some of you may find this useful.
