Ibis has only really been around a couple of weeks and is brand new by one of the Lemmy devs, so this is really a test to see how it functions and how easy it is to use.

One of the benefits is censorship resistance and also downtime resistance. If your favourite community has a wiki and suddenly that wiki goes offline, all the other instances will have a copy of that wiki, much like a lemmy community, so that information isn’t suddenly lost forever.
