Well after numerous times to get interested in twitter, I finally came trumps. Twitterfall is a superb online application developed to classify and segregate the information that you require based on keywords. Students or lecturers could use this to find the most up to date information on whatever subject they wish.
For example I have listed Modern Warfare 2 as my keyword and it shows up any tweet that mentions it. This has helped to view sneak peec videos etc.
