I owe you all an apology. For months now, I have been reading all your wonderful comments that come into my email box & then replying through that email's thread. It never occurred to me that those replies were not emailed to you but rather only posted on my site (thanks Disqus). I always appreciate it when I get emailed comment replies, and I couldn't figure out why no one ever kept the conversation going.
With Disqus, even though I reply by email, the comment goes straight to my blog. So for everyone who thought I was just ignoring their comment, it's not true! I doubt you want to go back & read them now, but they are there. Hundreds of replies that probably never saw the light of day.
This changes today. Anyone who enters their email with their comments is going to get an emailed reply (if the comment warrants it). But really, if you don't have an account at Disqus, why not spend 2 minutes right now and make one? They don't spam you and you can upload a pretty picture of yourself.
