User blog comment:Brandon Rhea/Introducing Unification, FANDOM's next big initiative/@comment-4636930-20181011180142

In my experience the thing that REALLY killed user retention is how mature wikis became increasingly frustrated with FANDOM's decisions like removing Monobook (yeah, GDPR, mhm, sure, how come other hosting sites still use Monobook?), forcing a disfunctional mobile skin that doesn't even allow editing, changing the domain, putting huge, obtrusive banners spelling "FANDOM" at the top, restricting the access to JavaScript (we've had to give up Google Analytics which was vital for analyzing how our viewers reacted to content, we also had to remove a custom article rating system) and much more. I have no idea what are up to with this Unification, but I fear the worst.

The point is – large and mature wikis need individuality and proper tools to do their best. There's really a lot of talented people that can make great use of JS, CSS, custom templates and more. When you make them frustrated, they leave FANDOM forever. If you manage to keep those people, they will stick around and contribute to many wikis. Don't waste your time on silly hubs, discussions and chats, people know how to communicate, they use Discord or IRC for that. Focus on not being evil, that's it.
