In a previous (and still ongoing) discussion it emerged that Fedora’s Live CD had removed Tomboy in its latest iteration. Tomboy has special significance to GNOME for reasons that were discussed here many times before, e.g. in [1, 2, 3, 4, 5, 6, 7]. Tomboy is a Mono application and it’s part of GNOME, which could — shall it be necessary — be complied without it.
Whether this latest omission from Fedora Live CD is deliberate or not, it would probably be hard to tell. Recently we saw also Fedora blocking Novell's Moonlight.
Without Tomboy, new users will be less likely to depend — practically speaking — on Mono applications and store their data in them. █
