Wow impressive feat! Thanks for sharing!

How many of them have you built/do you plan to build?

Since I've joined lemmy, I've been thinking about some kind of "community merging" feature.

A "meta community" would be able to "follow" other communities across the fediverse and posts from followed communities would show up in the "meta community's" feed. Posts from followed communities would remain on their original instances, or they could be duplicated to the meta community's instance.

There are a lot of details to work out, but I think this would add a lot more usability to lemmy and the fediverse as a whole

This is really interesting. Thank you for sharing!

Next step would be to add a way for app developpers to host special Instances that allow reddit accounts authenticated through oauth to interact with lemmy communities

There are far less than 255 countries in the world, and most countries do not have 255 regions.

On the other hand, most regions have more than 255 subnets, and with NAT these days, most subnets have faaaaar more than 255 devices

As long as you don't ask it to draw hands

Why would a main server be required if users can fluently interact across Instances? (which, imo, is an area where lemmy has the most margin for improvements)

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

While it's very similar to botw, it fixes a few things and introduces a lot of new fun mechanics. If you enjoyed botw, there is no way you don't have fun with totk.

The last two Zelda games (especially totk) lets the player get really creative as well

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
