Wave 4 of social media is already 17 years old. That was when Twitter initially came online.

Interestingly, Twitter was established before the smartphone went mainstream.

It was 140 characters because it had to be carried through SMS, and SMS had a limitation of 160 characters.

And the service wasn’t easy to use at first.

Obviously, all waves of social media were accompanied by big leaps forward in Internet technology.

Wave 1: Internet
Wave 2: HTTP
Wave 3: AJAX
Wave 4: Mobile
Wave 5: Self-hosting

It’s my belief that the “appification” of client-server software combined with inexpensive hosting will be a game changer.

Self-hosting obviously has bigger ramifications beyond social media.

Here's examples of self-hosted services that are downright revolutionary:

1. Nextcloud - File hosting
2. Etherpad - Notes
3. Moodle - Learning
4. Gitea - Coding
5. Collabora - Office

Not only is this software you can host yourself, it is getting less expensive and easier to use!

Beyond social media, what are the practical reasons people will want to self-host instead of pay for SaaS? Here's some reasons:

1. Most people own multiple devices. Client-server software makes managing content easier

2. Self-hosting is cheaper than SaaS -- especially when devices like the Raspberry Pi are involved.

3. Ownership of data. When you self-host, it's with the assurance that your data is truly your data.

But what happens when you add decentralization into the mix?

Mastodon is obviously the most famous example of ActivityPub integration.

But what's just as exciting to me is that WordPress, Nextcloud and Gitea are working towards including ActivityPub into their apps.

Certainly, both apps are already collaborative in nature. But once ActivityPub is turned on, they become decentralized *social media*.

That's the real revolution right there.

The possibilities for decentralized social media are endless. Imagine ActivityPub integration with self-hosted:

1. Calendar
2. Presentations
3. Project management
4. Wikis
5. Games

The Internet has now become exciting again!

The move to decentralization and self-hosting is going to kill a lot of big companies.

This always happens when there's a big shift in technology.

For example, Kodak couldn't survive the shift to digital cameras.

Sun Microsystems couldn't survive the shift to LAMP stacks.

Nokia couldn't survive the shift to smartphones.

The same will happen during this next technological shift. The first casualty will probably be Twitter -- but I suspect Meta won't be able to survive either.

I point out Kodak, Sun, and Nokia because they all have stuff in common: they were killed by a technology they pioneered.

* Kodak invented digital cameras
* Sun Microsystems pioneered web apps with Java applets
* Nokia released Communicator 9000 in 1996 -- one of the first smartphones ever

Each of these companies saw the future but they could not adapt.

Now what I find fascinating about Wave 5 of social media (decentralization) is that Twitter saw it coming.

Bluesky was spun out from Twitter in 2019.

In fact, Bluesky's first (maybe current?) CTO was Parag Agrawal -- who later became Twitter's CEO prior to Elon Musk's acquisition.

Nevertheless -- just like Kodak, Sun, and Nokia before it -- Twitter will not survive the next technology shift.

Why is this?

A good book on this topic is The Innovator's Dilemma.

Basically, Kodak, Sun, and Nokia lost marketshare because they sought to make high quality products for EXISTING customers.

Meanwhile, their competitors chased after "low value customers" with poorly developed technology.

Nevertheless, that poorly developed technology was iterated until it was able to go toe-to-toe with incumbents.

Does this sound familiar? That's Twitter and Meta right now.

Right now, Twitter is making the same mistake that Kodak, Sun, and Nokia made.

Elon Musk is chasing after what he believes is "high value customers" with what he believes is a superior product.

This is why he's charging $42,000/month for access to Twitter's API.

For now, Twitter might be a superior product to Mastodon. Maybe -- that's arguable.

But the tech that underlies Mastodon has been iterated, and now it's beginning to go toe-to-toe with Twitter.
