I've found Twitter to be a very handy tool for writers. I'm following a bunch of different authors, publishers, and the like, and very often they post great links to articles, blog posts, and other great material that helps with various phases of writing. Check various writing sites to see if they have a link to their Twitter page. Often writing sites offer the best Twitters because they're the ones giving the tips, not tweeting about what's for dinner or the like. When you look at the links they post, check the site for more Twitter feeds. You can get a good list of writing people to follow in a short amount of time. And, hey, maybe you'll pick up a good number of followers, too, so when you post things about your own writing, you'll have people that can check your stuff out. Easy networking, right? For example, I use Twitterfeed to get a link over to my blogs when I finish updating. After the initial set-up, it goes in automatically every time I post here or at Weird Happenings. Simple.
My advice is get yourself going in Twitter as a writer. If you already have an account, great, find some writers and publishers to follow (for example, Writer's Digest is a great place to start). If you want to follow me, feel free. My handle on Twitter is therav.
That's it for today. This was just a quick intro to get you to some of the great articles you may have missed other places online. There are a ton more ways to make Twitter work for your writing. Have fun in the Twitterverse! Until next time, keep reading and/or writing.
