Personally, it's been my (cynical) conclusion that a lot of times the bad-communication around code (e.g. lack of documentation/comments, resistance to PR feedback, closed architecture discussions), when it happens, can be attributed to motivations rather than lack of means.
But perhaps tooling provides more visibility around that and reduces the barrier for edge-cases.
in 2004 nobody shared photos of their lunch with their friends, not because it wasn't possible, but because it wasn't easy. last week i witnessed a teenage girl in a restaurant spend the entirety of a 30-minute dinner taking and sharing selfies. perhaps 100 in total.
it's my sincere hope that a reduction in friction gets us all talking about code more often.
currently, all code comments are declarative, requiring you to pay into the system now, not knowing if anyone will ever benefit from your effort.
with question-driven comments, you get answers to exactly those parts of the codebase that aren't clear, as it should be.
well that's the hope anyway.
