Great UI so far! I love the card-style posts on my feed, much easier to read than Mlem so far! My only question is what are the default posts being pulled? It does not seem to just be my Subscriptions so I assume it just pulling all posts from my server?

Unfortunately, Reddit can just keep doing that as often as they want. Fortunately though, there are few people who will actually be able to do a good job moderating especially for FREE. They will burn through the good candidates and have to rely on unqualified people to do a mediocre job. This will ruin the content quality and eventually kill the sub. So long term we may still win, but short term we will likely see little change. The problem is always the level of involvement of the general public.
