Thanks for the list, I plan to refer to it often. I'm always looking for new blogging ideas.
Depending on your personality and type of networking you do I think it is okay to combine personal and business on your blog. I wouldn't suggest going on and on about your kids or what you had for dinner but adding a few fun facts or trivia in about yourself is another way for people to get to know you. When people know you they are more likely to trust you. I think about my blog and online social networking sites that I belong to kind of like the the modern golf course. It's a way for people to get to know me on a more personal level, to get to know the person they are going to be trusting their life to basically. When I say Life I mean things like important passwords, bank information, etc in VA land.
My blog is business but it is also very random. I've had many people tell me that they like reading my blog because they never know what they are going to get.
Here is a blog that I think does a great job of combining business and personal:
