More and more I'm noticing I can't leave comments on some great blogs! If it's someone that I do not know personally - outside of the blogging world - I have no way of letting them know I think it's great. So, I decided maybe I'd post this and see if it helps. If you wish more people were responding to your posts, try this and see if you start getting more comments.
Go into your 'Settings' tab
Click on 'Comments'
Third section down is 'Comment Form Placment'
Make sure it is 'Full page' (not embedded below post)
Go all the way to the bottom & click 'Save Settings'
Try it and let me know if you see a difference in the number of comments you're getting.
