I'm the author of the gist. The submitter is a good friend of mine that felt like posting it, and I don't mind.

It was a reply I made to another friend and previous co-worker on twitter a while back that was talking about software estimation. It wasn't a comment on any other blog post or hackernews story.

I was thinking I should edit and elaborate on it into a full blog post at some point, but that would also require setting up a blog ;P I didn't take the time to write this up to the standards of an adversarial blog aggregation audience. And I don't care to defend it as such or in detail. It's meant to outline a broad point I think is true, but not to be ironclad in it's argument.

Anyhow, no cherry picking or anything unethical going on here.
