Dating-like apps come up in fedi discussions quite often. They have interesting aspects, for instance where obviously privacy is a big concern and where current generation of federated apps aren't adequate for dating. And how do communities / instances establish their trustworthiness? There are kinds of 'dating' were the requirements can be less severe. Like "Meet new Friends" kind of services where e.g. you seek folks for collaborative gameplay in some MMORPG or something.
