With my friend and coworker Mikz, the other day something came out:
"We could do a 'Today I Learnt' daily/weekly meeting, where everyone would tell the others in one sentence something that he/she (unfortunately 100% chances of he) learnt that day/week. That would be a nice starting point for ideas/brainstorms/discussions or just sharing knowledge.
I liked the idea so much that I'll start a section here, where I'll put this kind of stupid things you learn that you normally wouldn't share because "it's just in the docs", or "it's simple, you just have to use it once and that's it" .
We'll see how it turns out.
