Reputation, Revision, Policy
There are several reasons for this. First and foremost, they were unflattering to people I work with, whom I respect. The conversations actually happened, and happend pretty much as I described, but it's not fair to post something negative without putting it in the context of all the great things these people do for me and each other.
Second, I broke my own rule: Never say anything about someone else that you wouldn't want to get back to them.
Now, I'm frequently wrong about stuff, or say things without really thinking about them. But that reflects only on me, so when I do that (when), I'll just post a follow-up story. Making a fool of myself, I'm used to. It's how I learn best.
