I always wondered how much intelligence they gather from the Go playground.

Probably the data is too wild to make any use of, but then all the folks who have a clue using the playground as a kind of proof-of-concept play area... would be great for analysis.

Anyways, I'm not sure how well it would work, regardless of if it should be a thing at all. The majority of stuff I do, and the folks at work, we all have build pipelines that control internet access, use cache systems, etc... so I'm not sure it even matters.
