@odf,

Quote - When this goes public, I'm thinking about creating a registry of 1.0.1-compatible content on Antonia's official site[...] either I just trust the creators when they tell me their product is 1.0.1-ready (probably good enough) or I'll volunteer a group of testers to confirm that those products do indeed work.

I think in general you could trust the creators when they say their product is 1.0.1-ready. Might still be handy to have a bank of testers you can call on. Personally I don't mind testing the odd product here and there, but don't want to get heavily involved in testing a lot of content.

An alternative, or adjunct, to a bank of testers, might be a place where users could post reviews of Antonia content.
