In the next year, I'm going to start giving presentations to church and parent groups. I'd like to have a blog where I review various resources, share thoughts/articles, etc. I was thinking that I could have business cards or post cards printed up with my blog info on it, and people can go there to find more if they want. My knowledge of technology is not up-to-par at all. Is there a good how-to site for creating a high quality blog? Tips for improvement? Anything that might help me out?
