I must admit I haven't really gotten along with social media in the past; I don't have dozens of pictures of adorable cats to share and if wanted to spend a lot of time on a farm I'd go to a real one. However going down the self-publishing route means that I also have to think about promoting my own work, which rather implies that people have to know that I exist, and that means having a social media profile of some sort.
To that end I've signed up to Google+ and I apologize in advance for what is likely to be a very steep learning curve as I figure out how it all works. You can find me by searching for Mike Mullen. I'm the one in Milton Keynes UK the US Admiral who was JCS. :)
