We all like to talk with people who share our interests, whether it's the same book, the same music, or the same movie. But, if you're a writer, there are a few groups you might want to look into joining.
One is the SCBWI or the Society of Children's Book Writers and Illustrators
or the RWA or the Romance Writers of America
or Willamette Writers
and there are many more. If you write in a certain genre, just google it and you'll probably come up with some great groups you can join. And, if you do, you'll most likely meet more than other writers...you'll probably make a few friends. So, what do you have to lose?
