I recommend you to check out Gitlab. They are using their platform as a wiki to share what's going on in every unit, and publicly. It's amazing to see it day by day.
Ah yeah, I use Gitlab personally, but I can't change where the company I work for hosts all of our application code, unfortunately. I love how Gitlab makes everything public, though. :)
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
