Note: Not all of these are genre specific. Some publish a wide range of fiction and non-fiction works.

Secondly we have a few ezines, and magazines. I've never been a big magazine or ezine fan so the list is short. Just a few I have run across in my travels through the Twitterverse.
Last list is just for fun. Again it is a short list but these are authors, fans etc. who are twittering as SFF characters. Now some of these stay in character and even live within ongoing stories, others are authors who tweet as themselves, but they setup the account in the character's name instead of their own.

As always, input is welcome and appreciated. For example, I know there are more Fantasy/ Science Fiction character twitter accounts but finding them is not easy, especially since I am not a huge Sci-fi or Urban Fantasy fan.
Eventually, these lists will only be maintained on the Squidoo page (http://www.squidoo.com/TwitterSciFiandFantasy) as it is much easier to keep up and current. Blog pages get pretty much forgotten within days as new content grabs our attention. BUT....I will keep updating the blog posts, especially the authors and bloggers lists since they contain more then just the twitter link. (Facebook, webpage, blog, and forum link if I can find one.) So if you are doing research on an author or blogger, those will still be the best place to look.
