There are currently four site-policy questions. IMO three of them are about Jewish life and learning; only "Anonymity on mi.yodeya.com" is not. I say keep the three on main and detag them, and move the other hither.
As to meta, again, some are and some are not J.l.a.l.-related. In particular, IMO, "Can I ask questions about the talmud and Chumash?" and "Should I populate this site with questions?" are not, while "Mi.Yodeya. com for Children" and "False portrayal on an anonymous Q&A site" are. Keep the latter on main (and perhaps detag them?), while moving and detagging the former.
