joining twitter during the Iran protests in 2009, it imprinted on me the importance of twitter on a political and humanitarian level so that alone shows how important twitter can be. I also get majority of my news from Twitter. It also allows me to share many of my ideas, such as hubs. I've even connected with old friends, who even though we're friends on facebook, we communicate more often through twitter. On top of it all, it can be pointless, there are things and people you can follow for pure pleasure and entertainment, some people are very creative and will make your day in 160 characters or less! you just have to follow the right people!
