Very nice blog, I commented and I'm sure if you keep posting as you are you will get alot more down the road. I just started my blog and noticed not alot of comments but I know they will come.
I've wondered about this too. I frequently comment on other blogs but rarely receive comments on my own. One suggestion that I've read in this thread that I'm definitely going to strive for is to phrase my posts so that they are read more as a question. Maybe that'll prompt a bit more participation... Also I pulled the "Nofollow" code out of my Blogger templates a couple of weeks ago.
most people find commenting time consuming, which is usually why comments are so few and far between.
I only comment at do follow blogs. Just moderate the comments if you are worried about the spam and delete random xxx links.
