Is this not a common feature in other tools?
I really think one of the keys is peer buy-in. One of the ways to increase buy-in from your peers is making it less a chore and more a 'thing you get to do'. That's kind of the main inspiration for this, hence the "Build Boss" title and special slack channel.
That, and making it simple as a post-it. I don't think it's quite there yet, though.
