I'm aiming high :) If I could get 100 comments per post, I would REALLY be in heaven. I'd love to have a steady stream of interactive readers and commenters.
I guess on a normal basis our comments can get between 5-20 a post, depends on how frequently i've been posting too. I'd like to be ambitious and get in the 50-100 range, but I have "depressing content syndrome". I do my best to mix it up with the humor of life in general, but people know what they're getting into when they get any kind of emotional involvement with us.
1 is fine for me, per post, I just like to know someone is out there. My blog is just mostly my life with a little rant about something, here and there.
I'd love to average around 50-60 comments per post.
Check out http://metrodad.typepad.com. He gets a ton of comments for each post. One received 294 the last time I checked...now that's some active readership! I keep wondering if he has a huge family/friend base or if it's actually strangers (like me) reading his blog and posting comments.
