Call for Presentations is open, closes May 11:
https://thestrangeloop.com/sessions-page/call-for-presentations
This is one of the four big conferences I'm pushing to get Wikimedia developers to speak at this year, because there are great developers there to inform and recruit. Talks should be technical enough that they include code. You can do a 50-minute or 20-minute proposal.
They specifically ask for Semantic Web talks, so I think a Wikidata presentation would have a good chance of being accepted.
Strange Loop is September 23-25 in St. Louis, Missouri, USA. (I understand if the Wikidata team thinks this is too much of a distraction from their work and declines to submit a talk.)
