For anyone that is working to break into the biz, Author Culture is a great blog maintained by four seasoned authors. Lot's of helpful, fun, and interesting posts about being an author, no matter what genre you're writing in.
Wordplay is another fantastic blog for writers. Voted one of the top 10 blogs for writers for 2011, K.M. Weiland provides helpful tips through her writing and videos on how to finetune your writing, from developing them to creating memorable characters. From her blog, find links to several other helpful websites, for both readers and writers. Weiland is a favorite of mine because she's from Western Nebraska.
