I use blogger. I'm moderately tech savy, but I've known folks who are not that have done well.
Before you start blogging, I would sit back and determine why you want to blog. What are you going to discuss week after week--narrow scope of topics, or wide variety or somewhere in between?

How much time are you planning to invest in it and how often do you intend to post to the blog?

Blogger is free, so there is not cost.
