Hi David,
I like this post very much and I would love to read more! I am a collector myself and I post a regular piece here called the Comic Book Art - Traffic Review. If you continue to write on this topic, then we should consider starting a comic channel perhaps. I think our work could compliment each other nicely. Take a look at the Traffic Reviews on my blog if you are interested! (I wont spam your awesome post with links to my blog.)
