How do you know it was even read? Who knows what kind of settings Lew (or whoever you emailed it to) have on ther spam filters?
I once emailed Lew a snapshot that I thought he’d like for a blog entry, but as far as I know he never posted it. I assume that, for whatever reason, he didn’t see it or if he did see it he simply didn’t use it.
But I have to factor in the likelihood that: I got blocked by the spam filter - after all, Lew Rockwell doesn’t know me and I am only acquanited with him through his public works. And even if it did get through the filter, I can imagine him being leary of unknown people sending him emails with attachments. I also think it’s a little unreasonable to expect that he would invest the time to read and respond to unsolicited essays sent to him by unknown authors.
Now as far as getting more exposure… have you considered the Mises Community Blog Project? If the project gets off the ground, it might be the start of something big (who knows?) - and you’ve obviously got writing talent. Something to consider?
