We have plenty of different tags, but while having a look at some of them, I realised that we have some
- in plural: e.g. planets, gods, cities, humans, ...
- in singular: e.g. dragon, alien, spaceship, society, ...
I don't see any reason why we should have such a mix. There have been some discussion about it on meta, for example here and there (thanks HDE226868 for the links). There isn't a clear preference. Some even suggest to have synonyms between plural and singular forms.
I would prefer to avoid that. But what do you think, should we prefer singular or plural? In which cases? And if so, should we go on editing the ones that are "wrong"?
