There are probably very few entities publishing the QID about them in their twitter profiles (of course @vrandecic is one of them) but that could be encouraged, even as workaround for new twitter policy.
It's not necessary of course, Wikidata could be queried for #P4033 and #P2002. Anyone can help by adding #P4033 claims to the Wikidata item about your favorite marginally notable entities.
Are there any #twittermigration tools that leverage #Wikidata #P4033 (Mastodon address)? https://www.wikidata.org/wiki/Property:P4033
(Yes ideally it'd be #ActivityPub address; apparently there are some complications, see https://www.wikidata.org/wiki/Property_talk:P4033#ActivityPub_address)
address on the Mastodon decentralized social network (the form is '[email protected]' without a leading '@')
I guess this jump was from when the #TwitterTakeover was announced for the first time (or shortly after). Or maybe there was some bulk import of related data at that time...
Anyway, I guess there will soon be more than 2000 statements of #P4033.
How can I create such a chart (time evolution of a #wikidata quantity)?
@wilw this is the account that is listed on #Wikidata but there is no source or reference proving this:
https://www.wikidata.org/wiki/Q264699
using #Mastodon address (#P4033)
Is this correct? How can anybody prove that is an official account?
If you check a #seriousdetail:
#thatisworrying. I'm gonna find out more about this!
