also unrelated but the official lemmy app, jerboa, apparently publishes releases to the play store that are only compatible with the latest release of lemmy... so major servers that aren't updated to 0.18 yet are broken on it 
I think an influx of app devs will be a boon to the lemmyverse
Boost for Lemmy is also coming.
Boost for Reddit was awesome, so boost for Lemmy is going to be good if it's anything like the Reddit version
