I’m still new to lemmy, but if there isn’t such a feature, you should look at lemmy’s github repo. If there isn’t an issue asking for it, you can open it yourself

Why would a main server be required if users can fluently interact across Instances?

Nice point, I’ll update my recent post in this community to include a tldr

I don’t think a “main” instance is something we want. If one instance completely takes over the whole federation, we will have another reddit debacle in a few years.

While Decentralization is not a silver bullet against monopoly (just look at what gmail did to e-mails), centralization seems to always kill independence once platforms reach a critical mass

I think with the influx from reddit, which gathers a lot of technical users (which I think are also among the first users to migrate), I can see lemmy getting a lot more contributors in the coming days/weeks.

Among the features I’d love to see happen, some would also address your concerns about the lack of centralization :

• Community federation : this would make it possible to “fuse” communities from different instances. The admin of a community would be able to add other communities as “subcommunities” and all posts from subcommunities would show up in the “main community’s” feed. If the relationship is reciprocal, the two communities would “sync” with each other in some kind of way.
• “multicommunities” : users would be able to create and share lists of communities that span multiple instances
• Better community discovery across instances

I’ve never used peertube, but I heard it’s getting pretty good.

However, after considering hosting a peertube instance, I can see what a large actor such as Google can bring to the table for resource intensive services, such as video hosting

I predict that Reddit has already lost a lot of users for good. Only reason I’m going back is to promote lemmy over there
