Twitter reduces an issue to 140 words, brevity is brilliant, but a status update cannot explain the magnanimity of situations. My facebook or twitter status can do nothing to feed a million people in Sudan or Ethiopia or India or anywhere.
A blog isn't of much help either.
The internet is a place for fun, learning but not activism. It is a medium. Not a very serious one, I think.
Things gain undue importance over the internet. Trivial things like Paris Hilton exist because of the internet.
The world can be helped by making people aware. But considerations need to be taken.
The background of an issue cannot be highlighted. Sides are still taken. And in the end only the majority is right. It is not a just system. The 'opinion-takers', the ones who post earliest, become the right minds or whatever.
It doesn't make sense.
