I find that writing is good practice to to get my thoughts down coherently. And with a blogging habit, I find I can do it with much more ease, but it still takes a long while to re-edit something.
Editing is writing, however, and the hardest part of writing is thinking. I don't feel I've gotten much better at that.
These deletions have helped me realize why these essays bother me, on a stylistic level. The cadence is very regular and robotic. It's easy to anticipate the switches from descriptions of conventional wisdom to a different way of framing the problem, and easy to anticipate that there will be a conventional wisdom to roast.
The essays do have a lot of telling vs. showing, and maybe that gives them the feel of over-produced music. For instance, the paragraph about VC reactions to your suggestions in Why There Aren't More Googles would be way better as an anecdote with specific detail, imho.

Anyway, thanks :-)
