You've learnt some HTML? Well your one step ahead of me and I think I have managed to put together a decent blog.
I began with Blogger which is free and easy to use. Like Elenny, I would recommend starting with this.
I now use Wordpress which has many advantages over blogger, but can quite fiddly for beginners.
Oh, and another vote for Dreamhost if you are looking to register a domain/ host your blog.
