Hello,
Hello, Where can I find recent presentations about Wikimedia and what each
of the main projects is for? I visited outreach.wikimedia.org but didn't see slides or overviews. Thanks!
You might want to check out https://meta.wikimedia.org/wiki/Presentations.
It’s probably not super up-to-date, but many folks indicate a way to get the source ODP file (usually by contacting them, SlideShare link, etc).
