Angela Booth’s Life Stream

while you may think Twitter’s character limit is silly or frustrating, it’s actually born out of two other forms of communication that are widely accepted and used the world over. You may not think of Twitter being just like a postcard, but in some ways it is — one that you can instantaneously send to many friends or acquaintances at the same time. And minus the cost of a stamp.

If you're wondering whether Twitter can help your writing career, yes it can.

If you're a new writer, Twitter helps you to connect with other writers who can teach you how writing for money works.

If you're an experienced writer, Twitter helps you to network, and to build your platform as a writer.

And if you feel that 140 characters is much too limiting -- edit. :-)
