Each engineer knowledge is endlessly valuable, and I'm searching for a way to make all those hours spent on problems profitable by disseminating them amongs a growing team of ~15 software engineers.

We already have countless ways to do so:

• internal brown-bag lunches (BBL)
• a lot of blog posts
• regular hackdays with a demo to the team at the end
• local meetups, etc

But we needs to formalize this knowledge into a base that is easily searchable, discoverable, and easy to feed.

We've heard of Stack Overflow for Teams, also considering to open a Notion.

What do you recommend?
