Ask HN: What blogging site is best for me?

I already have a domain but I want some blogging site where I can host and point it to may domain. Wordpress asks for 10 bucks to do so.

I currently use Tumblr and I am loving it so far but the issue is, I doesn't have comments. I am using Disqus for comments which is fine too but since everything is rendered at client side, Google bot doesn't scan the comments and I dont get good ranking on Google :(

Any suggestions?
