We're playing close attention to Category:Proposals for strategic planning. Proposals we're implementing on this Wiki include:

There are a number of proposals related to the gathering of research that we think overlap. We encourage the creators of those proposals to merge them. We're hoping that Fact base/Research could serve as a landing page for implementing those proposals.

Regarding Proposal:Long term strategy development: This is a space for Wikimedia strategic planning. A five-year plan is currently being created here. This space could be used for strategic plans of other lengths as well.

We love ideas like Proposal:How to build a proposal review community, and we hope that people form ad-hoc committees. We've been experimenting with the ReaderFeedback extension as a way to introduce ratings, although it's reporting features leave much to be desired.
