There’s been the odd dampening remark here and there about Twitter in this blog along the lines that tweeting (this blog does not follow New York Times style rules) may not be the answer to every single one of the world’s problems. And 140 characters is a bit tight for some communications.

But for sheer bubblingly eloquent enthusiasm, try this essay by one of America’s top movie critics, Roger Ebert, which is a love letter to a web platform. He kindly helps us with his favourites, introducing some compellingly vivid Indian bloggers competing to develop a literary form last tried in Japan with the haiku. He illustrates very well what a powerful tool Twitter is for simply swopping information with links which make the 140-character limitation less important.
