Om Malik writes: Twitter, at its very core, is many things to many people: that is its beauty and that is its challenge. Twitter the idea and the product is ever evolving, and so is the company, which was and still is a work in progress. Twitter is unique because it was born in the crucible of failure and grew up in the glare of the spotlight. It took from its community, it learned from its community and sometimes it did shameful things.
