I sure have! 4,342 tweets and counting from the past four or five years. I still tweet regularly, follow about 150 of my friends, favorite businesses, celebrities, and news stations, and have about a 110 followers of the same. I think twitter is a social phenomenon that has really taken hold of the generation of people born in the 90's , as we were all in High school or starting college when it became a thing. I remember being very socially influenced to join it my freshman year of college because I was missing out on a lot of information - whether it be campus events or inside jokes between my friends I would have understood if I had an account. It really helps if your friends and organizations are a part of it, as I think this determines your level of activity on the site. I believe this is why it has been so successful - college and high school communities have really taken hold of it as a communication platform because it's what their students are using, and it's the quickest way to reach people with breaking information.
