Twitter for what it is which is basically 140 characters to come across meaningful and generate interest doesn't sound like it will get off the ground! Making what you submit popular so that people will follow you also sounds like a non starter! It does though and in a massive way as the site is hugely popular and for me it not only gives me updates from sites I actively follow/participate in but it also gives me in roads to the author. It's regarded as a site for the tech savvy and geeks but I think it's moving away from that and heading for the mainstream. Nothing could confirm that more than this morning my girlfriend signed up to see what all the fuss is about. Will it keep her interested for more than a few days? We shall see?!?!
