The technical merits of Wayland are mostly irrelevant
Today I read Wayland breaks your bad software (via), which is in large part an inventory of how Wayland is technically superior to X. I don't particularly disagree with Wayland's general technical merits and improvements, but at this point I think that they are mostly irrelevant. As such, I don't think that talking about them will do much to shift more people to Wayland.
