I belong to a number of professional loops and RWA. A group of fellow writers and I BLOG at http://romanticheartsandsexytarts.blogspot.com. If you want to stop by and find out what we like to read, we'd love to have you comment.
I frequent people.com, askmen.com, asylum.com, ivillage.com cnn.com, ibnlive.com and lots of others.
None. Well, except this one.
There are many writers blogs I visit daily. And the blogs of people with shared interests.
I used Critique Circle quite often before the current status of my life usurped all my time. I pop over onto authors' blogs, and agents' blogs, for inspiration and motivation, and to keep up with the industry.
Writer Unboxed is a nice, general writers' resource, as it collects articles, experiences, and interviews all in one place. Discourse via comments is useful as well.

I have a site on blogspot, where I share.
They are usually that sites that I have writen for.. other than that, i use forums, and blogs to express my self!
The wonderful world of blogs. My own personal one being ashleighrajala.blogspot.com . I also have an online bucket list, fortytwothings.blogspot.com , as well as a series of short stories I've written online: savannahstories.blogspot.com (but careful, it's an old edition and needs to be updated).
Twitter (twitter.com/ashleighrajala), because life is just like that now.
Facebook, because life was just like that last year.
And various sites that I comment frequently on, like totalfilm.com, guardian.co.uk, and others.
To some degree gather and facebook.
Currently I am an active presence on MySpace, Yuwie, and Facebook to share snippets of my work with a worldwide audience. I use those comments to help me to polish off my pieces. Also, I joined Blogspot to commune with other writers and learn all I can about their creative processes.
Just started with Facebook, Blogspot and recently World Pulse.
I talk to whoever will listen, mostly. I need to involve myself in more online communities, but I haven't found one that draws me in yet. I'm always open to suggestions.
