Because I’m much too lazy to make and link comment threads reliably, comments are now open by default on new posts. (We still reserve the right to close comments on certain posts for which ‘blog comment thread’ is the wrong venue for a productive conversation, but really, we mostly talk about procurement stuff right now, and on that topic, we already disagree pretty diametrically.)
Hopefully you’re more guilty now to leave a post uncommented. 😛
