I also can't really take this seriously. Maybe I'm ignorant of something to the Go ecosystem that makes this relevant, but this seems truly bizarre.

The "answer" microservice says: "Instant answers to any question" / "Ask a question and get an instant answer". Okay? Like, is this a service that I would have to back with my own knowledgebase? In which case this is just a service that accepts questions and serves answers? Why would this need its own service then?

The "address" microservice says: "Lookup UK addresses by postcode. Simply provide a valid postcode and get a full list of addresses". Why is this not called "uk-address" then? Or can it be modified for arbitrary locations? Does it handle when new addresses are created? Can it do validation?

How much demand is there for a "joke" microservice? And I think it shows a lack of professionalism to seed such a microservice with something like this: https://github.com/micro/services/blob/master/joke/examples....

It's real code https://github.com/micro/services

It runs on software that's also real https://github.com/micro/micro

It's hosted on a cloud platform with real customers https://m3o.com

Me too. However, I'm also not all that familiar with the Go ecosystem. Maybe they don't have the concept of libraries?
