Go Here and Here to see what I am referring to.
Mine are open and everyone here is welcomed to comment. Trolls, of course, get banned. But, most of the time, those who comment, are good people.
A blog without comment sections is not a community, it is a bully pulpit. I never want to be accused of running a bully pulpit. This is why I have comments here.
Just my two cents on that one.
