When I watch experienced people talk today, I catch the little subtle notes in between the obvious pieces of advice, and I find myself constantly thinking-oh shit, yeah, I experienced that, and this person knows what they're talking about; I wish I had known that two years ago! How is it possible that I missed all of these things in the past?
Bingo. And this is why I think giving lots of context is essential for good startup advice article. Most of the value is not actually in the advice itself ("Hire for culture fit!") which anyone could write, but in your own, personal, deeply useful experience that you brought to bear in a specific way, on a specific problem, in a specific context.
