Are you one of those people that continually checks your online party invitation to see how many people have agreed to come to your party? Imagine what that must be like for the people at Twitter that see almost 500,000 people sign up for their social broadcasting party each day. That little blue bird processes so many 140 character messages that by processing standards it only looks to Google as a larger player. Who knew that the "#" key would actually be able to rival the "@" key on the keyboard?
