Due to the only ‘comments’ I’ve received for moderation were spam, I’m only allowing registered accounts to post comments. That registration is free, and if the comments make me think hard enough I may even let you co-post here. After all, I don’t have the time nor the inclination to get involved with *every* meta-world. :)
Trackbacks and Pingbacks are also OK, and in my understanding are the common blogging method anyway. You can reach the URI for mine at the bottom of an individual post’s page.
