Why I not host your comments
Basically, because it involves a lot of work:
I need to review who got an account on MY site
I need to have the spam filtered out, which eats up CPU cycles
Most of us have their own blog, use the interlinking nature of the web!
My suggestion is: please post an article on your own blog and trackback the article on my blog you wanted to comment on. If you don’t have a blog: [use identi.ca] and url’shorten the URL of my article in your dent
