Many of us thought (read: believed) – including myself – that Wayland is the next-generation X.Org server for Linux operating systems, but in order for it to be that popular, it requires a big push from a ginormous project, such as GNOME.
As Matthias Clasen says in the email sent today to the GNOME mailing list, the Wayland project, which reached maturity recently, has a big potential, but only if it’s promoted by well known projects, and Canonical just failed to that by inventing Mir instead.
