Infancy. There is no guarantee it will catch on.

Edit: I find it strange that this image is implying that as soon as you stop implementing features you start dying. This is how you get needless bloat and turning solid software into something its original design never intended. A lot of software companies fall prey to this plan of endless expansion which eventually turns off the primary userbase of their software.

Lemmy doesn't need infinite features to continue surviving, but we definitely aren't there yet.
