I use Wikidata data (in a non-academic capacity) shrug

It's not that easy to work with, but there aren't any good alternatives in my case. Freebase died. DBpedia doesn't compare. Domain-specific databases don't have the data I'm looking for (or it's woefully incomplete and/or hard to link to external entities) because it straddles multiple domains, not to mention they're usually not free. I for one am very thankful for Wikidata existing and seeing good activity.
