Why are people obsessed with communities having the same domain name as their login? How do you expect these communities to deal with moderation and admin policies?

Here are some ideas for solutions to the real issues:

• Add smart cross posting like on Reddit where interacting with a cross post happens on the community where it was created.
• Develop mesh federation instead of a star topography. There would still only be one community with a unique name, but instances could share changes between each other, not just with the host.
• Provide a true cross instance community search that is integrated in the primary UI. It would need to provide better metrics for like-named communities so that users can make an informed choice.
• Admins need to stop land-grab communities. There needs to be a commitment to moderating, maintaining and growing the community. They could start by purging Reddit general interest knock-offs with fewer than 10 subscribers.
• Add support for instance relative links not only to communities, but comments and posts.

In general, I think user focused instances should be separate from community focused instances, but that’s a different rant
