Though I'd also publicly recommend to name this "telemetry" instead of "brag". ;-) There's some very interesting work to reference what kind of insights we could glean from this - compare https://telemetry.mozilla.org/ I'm currently looking into the policies used to govern access to such kind of data. https://wiki.mozilla.org/Firefox/Data_Collection has some insights, but that merely documents the kind of data stored, not how access privileges are handled. (And I'm concerned that anything that implies feedback on user actions might fall under the policies of the upcoming EU GDPR; e.g., Microsoft telemetry has recently been determined as such and needs adjustments in Apr 18's update cycle.) I've reached out to Mozilla to understand they, as another OSS project, handle this. Also, an open JSON endpoint on the Internet, what could possibly go wrong ... how do we ensure quality and authenticity of data coming in? Both as in protecting against malicious overload, as well as someone injecting bad data maliciously for existing clusters. If updates were signed with a recurring key, for example, it could be determined automatically that it's indeed always the same cluster submitting, and it could also serve to control access to that data (such as rights to delete). > > Very cool!

We may also want details on OSD variance and weights. On the other hand, the "crush_rule" one is not so useful without knowing what the rules are, I feel.
