Well, being a mom of 3 boys, running 4 blogs, contributing to 2 other websites, and running a ranch...I don't have time to respond to comments unfortunately. I always try to write a post telling all my readers how much I appreciate them, etc. It's the best that I can do for now.
I'd hate to think that you would never visit that site again at all because of that. You have no clue what they may be going through in their own personal day........
Oh and as far as checking out the blogs of people who leave comments, I need to get better about that, too.
Altho I have to say that I've been told a way to increase traffic is to leave comments on the popular blogs. It just seems insincere to me. Leaving a comment in a blog just to get traffic to mine? Maybe some of the more popular bloggers have figured this out and think people are just fishing for readers?
