Twitter

Introduction
Twitter is an online service where you go to update on your life. It is built around one question most of us ask: "What are you doing"?

Ideas

 * 1) The 140 character limit should be removed or heightened to something like 256 characters. I often have trouble telling people what I'm doing in less than 140 characters. Also, people don't always use twitter for status messages; sometimes, they use it for comments on life, politics, etc.
