I just went to Comment Moderation and found months' worth of unposted comments. Apparently Blogger is a little sketchy about informing me when one has been posted. I have approved and posted the comments at long last. Sorry. I really can get the feeling no one is out there, and the few notifications I receive are just from the rare passer-by.
Rest assured I will check the bin more frequently now. I'm psyched to have any readers, let alone any willing to chime in.
