Why would anyone want to post a blog here at recruitingblogs and then censor any comments it might attract?
Wouldn't that change this site from one where people engage, to one where people just broadcast?
The author of this blog has chosen to delete comments.
I doubt there is a better way of illustrating that the argument presented in your blog post has absolutely no intellectual rigour, than censoring comments.
Dumb doesn't even begin to describe this kind of behaviour.
Here's a tip for all you budding HR/Recruitment bloggers. If you can't back-up your argument, stay away from posting stuff on the Internet.
