Category:Jewish wikipedians doesn't help collaboration, so it's out. Category:Wikipedians interested in Judaism is in, because rather than identifying the wikipedian, it helps you find collaborators to work on pages. The distinction is rather subtle, and rather pointless, but such is life.
Jewish Wikipedians might be presumed to have a certain shared viewpoint or bias, whether or not they are particularly interested in Judaism, a viewpoint or bias not shared by non-Jews interested in Judaism. Put like that, it seems a total fallacy actually (compare Jewish editors such as Jayjg, IZAK, Newport, Mibelz, Lulu of the Lotus-Eaters and non-Jewish ones interested in Judaism like RachelBrown and Sheynhertz-Unbayg).
