I had a similar question the other day. I asked a few people and no one seemed to have a good collection to point to.

I specifically like reading posts by people who post regular retrospectives (weekly, monthly, or yearly).

So I started [0]. It only has three entries right now (including the one you mention above), but I would love to see contributions via pull requests.
