great article overall - but starts off by saying 'do not cargo cult this' and then proceeds to proscribe many 'mandates' without giving any rationale behind them..
1) give an bcc/perf example to check the need for tuning and verify its effect.
2) give code/docs/paper reference as an embedded link.
3) give a generic monitoring guideline at the start of a "chapter".
Seems like I've (at least partially) failed. I'll do better next time.
