I am a member of a few sites where I don't bother posting anymore. Some of them email a weekly digest of articles and some images.
FStoppers had an article explaining the Quad Bayer Filter that I think is worth a read for those who don't already know about it.
Thanks for that. Alex Cooke does some really good articles.

Very good article, he even remembers about Foveon :)
Just minor inaccuracy there - every sampling system (what digital sensor is) needs some kind of antialiasing (AA) filter. For high pixel count sensors lens diffraction itself can be enough to smooth higher spatial frequencies out, also for still image some aliasing is tolerable, makes image crisper. Foveon sensor without AA filter just does not create different color aliasing artifacts, which are most noticeable - otherwise it makes slanted lines aliased as well.
