Just a point of information, re: "However, out of 18 Wikimanias so far, most of them have been in Europe..."
Wikimania has been in Europe five times in its history and has been held outside of Europe ten times. This means only 1/3 of all Wikimanias have been in Europe.
With no disrespect to anyone on the list, I feel this illustrates how Wikimania's perception differs each year to a different set of attendees as it moves around the globe to expand our engagement. Wikimania has changed as the movement has changed in the last 18 years. This includes fostering deeper collaboration, engaging new communities, the rise of GLAM wiki and cultural partnerships, or simply connecting on a human level face-to-face, which we cannot do over Zoom.
I'd encourage folks to attend the office hours for Wikimania to learn more about how this year's Wikimania is a very different concept than in the past – it is a regional collaboration of ESEAP, and next year's is a regional collaboration with CEE. In this sense, the conference has already adapted to the ideas that JB and others have alluded to – a super-regional conference that aims to keep the hybrid elements we've used during the pandemic while encouraging regional collaborations. Stay tuned for more details as this year's Wikimania organizers announce even more plans for the hybrid conference.
