I love it.
Google+ is Google’s social networking attempt. I have been on for less than a week, and I love it. Here is my profile! http://gplus.to/MariMiniatt
Just from a writers standpoint. It has a lot more functionality, than Facebook. There is no character limit to what you post, so you could post snippets of a work in progress. And who you share it with, is a plus too.
G+ uses circles. You set up a circle for a certain group of people. Such as family, friends, writers, beta readers, etc. You can choose who sees what post. There is a public choice as well. That one allows your posting to be seen by everyone and searchable.
I said beta readers. That is one of the first things I used it for. I have a group of ten people that are beta reading Minstrels for me. I added all of them to one circle. Not all of them are on G+, but when I send a post out. They get an email. The ones that are on G+ can respond below the post. The ones that are not can send me an email. A nice combination of forum and email communication.
What about selling? Haven’t tried yet. But your profile would be best for that. Links to your blog, links to your books. You could set up a circle of people that want to hear about any deals you have, and when you do, send out a post that goes public and to them as well.
I am still messing with it. I asked a question this morning and got wonderful, educational answers. There is talk that blogger will be phased into G+ as well. That should make blog posting easier for us that use blogger.
It will be going public at the end of this month. Right now, beta invite only. I have invites. If you are following me on twitter @mariminiatt DM me your email, and I will send you one.
