I think this style of teaching has great value. Someone who's learning something themselves is the person most suitable to teach it to others, since they know exactly what a novice user doesn't know. For example, I wanted to write something up for monads the other day, since it's a simple concept that's made super confusing by people who dive into mathematical notation right away. The downside with this approach is that the novice lacks experience, so what they're learning may not be entirely accurate.

I think the best approach is a hybrid: Someone who is learning the material explains it, and someone who already knows it points out mistakes. In this case, HN can serve as the expert, and we all end up with a very informative post.

One of my great regrets with leaving my last job was that: I had little FP experience, and we had one guy with a lot of it. We had done informal teaching sessions, and had planned to try to write blog posts / record podcasts of our little sessions, precisely for the reasons you mentioned, hoping that it would help others absorb the material more easily.

Why can't you still do it? I'd read that.

There's probably no reason I can't still do it, aside from physical distance problems and getting the free time lined up on both sides, which was far easier when we could just schedule it during working hours as 20% time.

If we/I ever do it, I'll make sure to send you a link. :)
