To Tweet or Not To Tweet

That would be the question. I first attempted to research twitter, to find the pros and cons of using it, but I find I'm unable to check out anything but the sign-up page without having an account. When I tried to create an account, it tells me that I cannot do that but it doesn't say what I cannot do. I did find that it is a social network based in San Francisco that allows for quick burst of information shout-outs of maximum of 140 characters they call tweets. It is suppose to be great for putting your business out there to help build relationships between you and your customers. Twitter is accessed all over the globe in 20 languages. Twitter also has many forms of mobile access, mobile apps as well as SMS messages. And of course, like Facebook, Twitter can be a good way to keep up with family and friends.
Personally I have chosen not to do twitter because I feel that there are a lot of social networks out there and my entire family is on Facebook so there I will stay (I just don't have the time to keep up with so many websites and I'm already having a hard time keeping up with my Facebook).
