I particularly like Smart Bear's Blog interface. It's easy to leave a comment, sign up, low barrier of entry to leave a comment, and it's easy for others to chime in on comments. I like the clean basic look, the layout, and the variety of sharing features.
I'm going to add a blog section to my site and I'm looking for a platform that will be easy to use like the aforementioned blog above.
In your opinion, what's the best, easiest, and cheapest blog platform similar to the one i've just described?
