I'm loving the writing sites I've found on Facebook! Writer's Around the World is a great group just there to talk about writing. Nirvana. They also have rules about what can be posted on which day and that helps keep the group on track. Well done, WAW. You guys rock!
Indie Author Group is another good one dedicated to Indie authors. No promo just exchanges with other authors talking shop. I love it.
I've found a few others and most seem great. The ones with promo rules are best. As writers wanting to shamelessly promote our books, we need a little restraint!
There are also reader-author sites to connect with readers and share you work. I do a little of that too.

So tell me??? What's your fav writing site? Link us!
