It's exciting because it's Wayland. What more is needed? Why get excited about anything? Why get excited that a phone has a quad core cpu, that allows you to post twits on facespace one nanosecond faster? Why get excited because Apple offers their same-old phone with new colours (which other manufacturers have been doing for years)? Why get excited about baseball?
And what is the exciting thing about running Wayland? I've seen this idea in a few places. It's a piece of completely utilitarian, behind-the-scenes software. I could never figure out the hype.
