I was thinking about this the other day and it’s good to see a project like this.
Although it’s early days, I could see people skipping establishing their own forums and, instead, setting up their own instance because it gives your forum a much greater reach.
The tricky bit would be in migrating existing forums over here. If you had your own instance it could be doable once the relevant scripts had been perfected - you’d just be moving information from one database to another. As I’ve overseen a few migrations of forum software, I know that’s easier said than done but not impossible.
It’s definitely an area I’ll be keeping an eye on.
