Why should I use a Twitter?

A lot of people ask the question "why should I use a Twitter?" rhetorically, with the mindset that it's a bunch of useless information they don't need to know or that it's good for stalkers. I added ten people to my "following" list on Twitter just now, and there are different types of "news" I am going to receive from each person. Some people call it useless information; I call it news.
First I added The TV Guide and Funny or Die. I can find out updates about TV listings and more , and I can get links to hilarious videos without even having to go to funnyordie.com. Looking at my "following" list I realized I wasn't following any actors or actresses. I added Bob Saget, Ben Stiller, and Kevin Spacey. If you like a certain actor or actress you can get updates on movies or shows they're working on, and shout outs about other things coming out. For NBA news I added Paul Pierce, Steve Nash, and Derek Fisher. Pierce so that I can get Celtics news (because I'm a Celtics fan), Fisher so I can get Lakers news (I hate the Lakers but keep them close), and Steve Nash because he is second to Shaq for the funniest person in the NBA. To top it off I added Conan O'Brien and Snoop Dogg just for laughs.
A lot of people don't realize that you can get actual real news from Twitter, and sometimes you can get that news before it's even published by the mainstream. I used to think it was useless until I tried it, and I've come to realize that almost all of the people who say it's useless have never tried it.

Twitter Dissapointment

This week was my first Twitter experience and to start I 'followed' some famous people including the likes of Shaq, Bill Simmons, Chad Ochocinco, and Roger Ebert. Right off the bat I was troubled and discouraged by the fact that people pose as other people. Why would somebody pose as Shaq? Why would somebody pose as Roger Ebert and tweet fake half-ass movie reviews? Don't people have better things to do?

I have heard so many good things about Twitter since it came out, and the first thing I see when I start my account is that there are ten versions of every celebrity. Yeah I understand that I can find the real one by shuffling through and looking at how many followers each one has, but that's bullshit that I even have to do that. Twitter needs to find a way to control this.

Another thing about the celebrities is that only a few of them actually post things themselves. You can tell when it is actually them. I wanted to follow NBA basketball journalist Michael Wilbon and he has a twitter ,but it is just a machine that quotes everything he says in his daily ESPN television show 'Pardon the Interruption.'If I wanted to know what he said on his show then I'm just going to watch his show.

I guess I am just confused with a lot of the hype. Maybe if I start getting some followers and follow people I know then it might be a more useful experience, but for now I am dissapointed with Twitter.
