I stayed at a Hilton in Vegas that had a TV with unchangeable inputs.

You could always just use a github repo as a wiki. It would render markdown pages in your browser, and it comes with built in version control!

There’s no more barrier to spinning up one’s own email server than there has ever been. One simply needs, at a minimum, a server in the internet, a DNS domain, and know how.

A server on the internet has never been easier, thanks to cloud providers. In fact, many cloud providers will give you a working email server, so that you don’t need to do all the sysadmin things to get software like Bind or Postfix up and running. These hosting providers make it pretty simple run your own personal email server and domain.

The big providers are successful because most folks don’t want to stand up their own email server, they just want to use email. But anyone can go it, if they have the time and interest.

I don’t think “destroying” is the right verb. According to https://fedidb.org/ we can see that at the time of my post:

• the Fediverse has 9.2 million users
• Lemmy software nodes have 135,410 users
• Beehaw has 12,365 users (9.1% of all Lemmy)
• Lemmy.world has 23,756 users (17.5% of all Lemmy)
• The remaining users are spread across 358 other active servers

Lemmy and the Fediverse are going to be just fine.

I’m guessing Beehaw will lose its explosive growth of late and shrink back into a very niche community that few people care about. I spent a few weeks there, and I suspect this is just fine with the admins. It’s a nice place and I plan to visit now and again, but I’ve effectively migrated here as my new main node.
