Might I recommend that everyone catches up with the proposal on Meta, for context, before continuing discussion here. I have included the concept picture here.
There might be more Wikimedians who stumbled upon Wikimedia Space without the proper orientation, like me.
Also, there seems to be private (hidden) pages where development is discussed and issues are voted on - in the interests of the maintainers’ sanity, and to avoid duplication, I would guess that asking for an invitation there might be the right course of action for those interested in taking part in discussing the evolution of this space itself. Edit: Quickly pointed out by @ELappen_WMF is that all discussion is happening here in public, bar one or two issues with legal implications - to which the proper sensitivity and introduction is needed - I’m thankful that I we have experts to deal with those - much more fun focusuing on the practical things we’d like to see.
I would also highly recommend reading the FAQ on Meta. An excerpt:
Can content from Wikimedia Space be followed from MediaWiki wikis? edit
This is a goal for this project. We will have a better assessment after launching this platform.
Thanks to all involved, so far.
