Hi Ryan,
Sorry for the delay, a lot of work came in between.
> I actually suspect that the proposals that will get the most votes will be ideas that benefit the most projects.
Still, a large community like the English and the German community have an overly weight on the balance simple by the fact they are with more people. I think this unbalance has a larger effect on the votes than the factor if the benefit of the most projects. The idea of that the ideas that benefit the most projects get the most votes is in the ideal situation a really great point of view, but such requires high penetration in the communication in reaching the users around the world. (This seems almost a request for improvements in the communication as bug first, and while that would be great, that is not the point.)
Maybe I should explain why I write this. In my area I organise a lot of courses, writing sessions, etc and with organising this we notice that for new users the provided online working environment is almost completely (yes, that worse) insufficient to continue editing. We also notice that existing users have found their working environment and do not care much about the difficulty new users have, as they often seem to think: I can, so they should too be able to find it for themselves.
The we is just a few people who organise most activities and see the effects of it.
While almost everyone in the movement think editor retention is important to improve, because many do not have the experience in organising writing sessions, workshops, etc nor are out for feedback from new users why they actually stop with editing, they do not realise that Wikipedia is missing something for new users. And those new users are already gone or do not speak out mostly...
If you think you like to continue with the votes for the ideas that are considered the best in the movement, I would like to suggest at least one change in set up: organise it in such way that you create categories. Like a category what the Wikidata users need, what the existing editors on Wikipedia need, what the Commons users need, what the organisers of workshops/writing sessions/etc need, etc.
Greetings,
