Here is another suggestion to help make the Wikimania region selection a *community effort*, rather than a competition:
It would be nice to see coordinated efforts on local issues in the months surrounding a non-US/European Wikimania (assuming for the moment that the US/Europe can take care of their own issues). For example, volunteer days concentrating on eswiki and Spanish localization issues in the months leading up to Wikimania 2015. Otherwise it feels that Wikimania can be just a "tourist visit" with little long-term contribution.
It's important to note that building the *community* required to host a Wikimania is indeed a worthwhile achievement and does have long-term influence. So the area for improvement I'm discussing is a broadening to technical or content issues. For example, deciding to adopt Mexico-related entries on eswiki, or some feature to better support <translate> for Wikimania content. The coordinating committee could "adopt" certain projects or features for the year.
In my ideal world, Wikimania would be the culmination of a year-long focus[*] by the broader movement on a specific country or region, with many coordinated events planned, content written, and technical features implemented in anticipation of the conference. --scott
[*] With the three-year rotation, perhaps this could even be a three-year focus? But let's not jump ahead of ourselves yet.
