IANAL, but this is my understanding: if your site is publically accessible, the exact nature of your changes to the core software must also be made public, since the GPL forbids you to have users who cannot build further on your changes.
This is incorrect: you can modify the software any way you want, and use it for whatever purpose you want, without making anything public. So a site does not have to make its wikimedia-derived software public.
If you redistribute the modified software to other parties, either for free or selling it, you have to use the same GPL license. That is, you must grant the same rights and obligations of free use, free modification, and GPL redistribution.

Oops! Of course - I somehow muddled using the software in a publically visible way with distributing the software itself.
