But what is X11? Is that like Wayland? ;-)
Others have mentioned it was a directory, but it sent me off on a nostalgia trip, so here is an "obituary" of sorts, that is itself getting rather old:

And here's the HN discussion from back then:

None of these really convey the cultural importance of Freshmeat to the opensource community at the time, though. For a while, Slashdot + Freshmeat were among the two first sites almost everyone I knew and worked with would open in the morning.
Imagine if GitHub release authors publicized releases in a timeline view.
v.0.1 of this or v3.0 of that had the same exposure.
One site. Daily fix.
Network monitoring/visualization widgets that sit on your WindowMaker dock or similar was a common theme.
So that is sort of the reference being made here
