Twitteriffic Premium is the iPhone app that I use so that I can send Tweets to Twitter. Twitter is a great microblog (in 140 characters or less). It is on the 1st page of my iPhone and it is one app that I use multiple times every day. I have met many fellow educators over the years at conferences and you can keep in touch with friends, family and colleagues with little or no effort by using Twitter.
