Bob,
If he answered every email he got he'd never get any amps built. I've seen the man's inbox, it is a scary, scary sight. I hear what you're saying though about the chain of communication but seriously, he'd be answering emails all day every day.
Here's a funny, vaguely related comparison for you - for the most part I've stopped posting pictures of the stuff that I build on Head-Fi simply because of all the idiotic PM's that I get afterwards asking if I'll build someone something, where I got parts, how I did this and that, etc., etc. I can't imagine what it's like for someone like Mikhail.
