@tk Actually looking again, what apparently ~all except GnuSocial fediverse implementations are doing is forcibly adding "Hashtag" into the ActivityStreams namespace…

@evan @cwebber: Given how widespread this usage is and how it's unlikely to change, what do you think about updating ActivityStreams documentation to properly match usage? (Not that other things should be done this way)
Like https://www.w3.org/TR/activitystreams-vocabulary/#microsyntaxes gives an hashtag example without qualifying type and that seems pretty wrong to me (and might be where GnuSocial got it's idea).
