Guest blogger Sandy Nathan likes social networks for reasons other than you’d think.
Facebook and Twitter are invaluable writing aids. Having to create a convincing, emotionally compelling message in 140 characters is a terrific exercise. Ditto fitting your message onto Facebook with its limited number of lines/characters to accompany an initial post. Just pruning your "too long" message to fit is a great discipline. (I love the way Twitter says, "Over 140 characters. You have to be more clever." You do.) Then apply the above to everything you write.
Sandy writes fiction and nonfiction for both adults and kids. She likes challenging herself with contests, and so far has won 17 national awards. Her website at http://sandynathan.com has links to her blogs and other helpful information.
