Prometheus is a (rare) recent example of a significant, thriving open-source project that is community-based. Not quite as broad in scope as something like Elasticsearch though.
OP here, my bad indeed.
I was fiddling around trying to figure out the right way to shorten and carelessly ended with this. No intention to mislead, but I agree this changes the meaning in a bad way.
Most importantly I don't see a way to revert; hopefully the moderators will see this and do it instead.
It's taken from close up so you see how a concrete platform has been poured under the building, then the whole thing pushed on rails.
