Maybe it can suggest an app and other "getting started" stuff through a system message of some kind, like how Reddit delivers notices via it's /u/Reddit bot.

Definitely there should be an updated list of apps as the first recommended app (Jerboa) is like... Pre-alpha. Constant authentication issues for the one day I used it, plus other usability issues galore.

I only found any mention of Connect for Lemmy on Lemmy itself and it's a far superior app, used it ever since.
