I became aware a few days ago that Facebook will change their API and
MediaCore's Facebook comments will stop working in June (they already display
a warning). I'm currently pooling customers to get a project budget to migrate to the new Facebook code and I'd like to invite you on that.
I'll update the Facebook integration so the comments will work in the future. I should mention that your existing Facebook comments might be lost during that transition because Facebook but that's a Facebook issue - as far as I can see the new API does not allow getting the old comments (changed IDs).
Depending on the number of participating customers I can also add new features, e.g. a full Facebook like button integration to (optionally) replace MediaCore's liking system. Optionally I can adapt the patch to the MediaCore version you're running on your site + deploy the patch for you.
Of course the new code will end up in github but because of early vacation this year I can't guarantee I can do before June.
