Now that I have a fancy new phone, I decided to try Twitter, a cool service that allows you to keep friends updated with what you are doing at any particular time.
The concept is simple. You login and type a quick update, like "I'm eating a cheese sandwich...and it reminds me of summer." Or anything you want, really. But it can only be 140 characters long. No blog posts, no novels. Just a quick blurb. The cool part is you can use your mobile phone to text in your update, and receive updates from friends or people you are "following".
I added the Twitter feed to the top of my blog here, so quick updates will show there, while full blown blog posts are shown here.
