Twitter

Is it vital? Do you have it? I do (@dragon30125) but yet I rarely tweet once a week, if that. Twitter's use in crisis', politics, journalism and for celebrities has been beyond proven and I am not going to sit here, type and link you to a thousand facts that you've heard or seen before. But I really want you to think about whether or not we NEED Twitter.
Forget that it allows a celebrity to possibly respond to your question, forget that multiple business' are now advertising through twitter accounts forget about the joke accounts like @God_Damn_Batman that may cause you to laugh or chuckle, heck maybe even “lol” or “rofl”. Ask yourself do we need twitter? We have phones that can text at 10 more characters, Facebook where our favourite celebs have official fan pages for us to follow and YouTube where joke videos are posted all the time that make us “roflmao”. So if we have all of those that already cover the grounds that Twitter does, then what use is Twitter?
I am not saying that twitter is useless, after all it does combine texting, Facebook and YouTube into one big old ball of one-stop-shop. Twitter does allow us to seem like complete morons to the Celebs that we idolise whilst offering the chance for them to get to know us, hence why we follow them. Twitter does allow us to quickly hit up our friends if we’ve gone over the cap on our mobiles and make us seem like complete morons to them, hence why we follow them. And Twitter does have many people who are willing to make fake accounts and tell jokes for nothing more than amusement for their followers who reply to make sure the entertainer knows they are a complete moron, hence why we follow them.
So that is why I ask you if we need twitter, or do we want it? That is what I want to know that is the crux of my question, why I raise all these points to ask you: Is Twitter vital?
