Reddit refugee here. Using Boost for Lemmy on Android.

1. It is VERY difficult to find interesting communities from within the Boost UX. No “You may be interested in” suggestions are thrown. I used a website to find the Reddit equivalent of some communities. But certain ones not on lemmy instances could not be added using Boost.

2. No infinite scroll/doom scroll. The number of posts peters out even though I am subscribed to maybe 5 dozen communities.
