Although I can understand your not enjoying this particular letter or agreeing with its inclusion on a blog named Letters of Note, to hear you then use that as a stick with which to beat my entire website - a website you admittedly know nothing about - does smart a little. I'd suggest maybe having a poke around; you may come to the conclusion that today's letter simply wasn't to your liking and that, actually, the website does have some value.
I guess the snide remark didn't contribute anything to the point of my original post, and that that post would've been off just as well without it. Well such is the nature of a forum - I would like it too if I had hours and hours to hoohah over each sentence I write and get to compile them into nice internally consistent and rhetorically perfect masterpieces. Alas I'm just a programmer posting in between compilation and simulation runs, so the style is much more conversational, and conclusions are often more haphazard than any that would stand up to rigorous scientific standards.
