Our gaming community switched from vBulletin to Discourse in 2016. We got A LOT of bad feedback from the MINORITY of users. And you know gamers, they can be really vocal about changes or things that are not as used to be, or when they don’t like it. Some kind of ‘entitlement’ comes with the gaming audience.
The vast majority of negative comments were about: pages replaced with infinite scroll and how narrow the width of the new forum was. And then the same users were repeating the same points again and again until some of them stopped complaining and some of them left the forums.
Once we started educating the community about Discourse features and how advanced are some of them comparing to vBulletin, it didn’t take long for members to start using them and embrace ‘new things’.
You can’t make everyone happy with the change, but you need to be persistent and discuss it with the community. We had one topic where we encouraged people to share with others which useful functionality they discovered. That helped others understand how Discourse works or how to do some stuff on their own.
