Generation of 140 characters

Discovery of twitter and facebook have been revolutionary. It gave world a new way of sharing where governments across the world couldn't censor the information to save there own asses. But the witch hunt has already started as well; attempts to block them. Anyway, beyond that I see another trend is new society after evolution of this social media. This society has short-term memory; how so much important an issue is as soon they are out of "trending", nobody gives a damn shit as new topic is already there. The other problem is the over-dependence on these sources. If a big crowed has started saying something, just reading those 140 character tweet people enrich their knowledge. May be its more tasty and easy way to handle the information, but there is always whole lot of background needs to learnt, only headlines are not everything. And this I think is very big problem. This is going to slowly kill the practice of researching the matter as most of us are learning to believe what is said is true and enough within its 140 characters itself.
