Having it present a handful to choose from (lemmy.world, lemmy.ca, lemm.ee, kbin.social when it gets supported) would be a good idea.
Or just have it pick a random one that isn't defederated from most others on first load since it doesn't really matter anyway.

I've found the people I know that use third party apps are much more likely to post links and content as opposed to just lurking.
Is viewing kbin instances fixed?
Isn't there a bug in the new version of Lemmy that messes up federation with Kbin right now?
Most subs hosted their content to external sites anyway from what I saw due to how terrible reddit's video player was.
...Lemmy is free.
Also the one time payment model was how sync funded itself until now.
