In theory, Discourse is great. We pay them a fair bit of money but they keep the forums updated and secure on our own hosting. However they have a different outlook from us (like when the Google search thing was added). There also seems to be more and more reliance on their CDN for resources, which is an iffy area for us, as it could be harmless, but also could be used for tracking. We’d rather be using a trustless system.
Hopefully, what we’re working on with Indienet could end up replacing the forum. Changing over will have some level of hassle, and we will have to work on a way to archive what has been discussed here, but we’ll cross that bridge when we come to it!
