'"More than 70,000 users joined Mastodon on the day after Musk's Twitter takeover announcement," writes Slashdot reader votsalo. "Mastodon is a six-year-old decentralized social media platform that uses 'federated' servers." The Guardian's Wilfred Chan writes:

I joined Mastodon this week, and it took a few hours just to master its new vocabulary. Some of it is a little silly-sounding: instead of tweets, you have "toots". Things get trickier after that. Mastodon is not a single website but a network of thousands of websites called "instances", also called servers. These servers are "federated", which means they are run by different entities but can still communicate with each other without needing to go through a central system. And the space they all exist in is called the "fediverse," which some savvy tooters call "the Fedi."

When you sign up for Mastodon, the first thing you do is choose a server. There are general-purpose ones, such as mastodon.social, as well as ones aimed at interest groups, such as kpop.social or linuxrocks.online. There are also joke servers like dolphin.town, where the only thing users are allowed to post is the letter "e". The server becomes part of your username (for example, wilfred@kpop.social), and the toots you see on your feed are toots from your server-mates, rather than from the entire fediverse. But you're also free to toot at people from other servers and even "boost" their public toots on to your feed.

That's how Mastodon creates a unified global experience without being controlled by one entity, said Eugen Rochko, Mastodon's Germany-based founder and lead developer. "The servers are service providers, like Hotmail and Gmail are for email. It doesn't mean that the different servers are isolated from each other, like old school forums," he said. "Having just one account allows you to follow and interact with anyone in this global decentralized social network." But Mastodon's model comes with its own risks. If the server you join disappears, you could lose everything, just like if your email provider shut down. A Mastodon server admin also has ultimate control over everything you do: if for some reason the owner of kpop.social doesn't like that I boosted a toot from dolphin.town, they could remove it or even "defederate" the server, which would block all dolphin toots from the k-pop server completely. A server admin could also snoop on my private toots if they wanted to -- or delete my account for any reason.

While Mastadon's 70,000 jump in users sounds impressive, it's "still a drop in a bucket compared with Twitter's reported 450 million daily active users," says Chan. The decentralized software also remains difficult for many people to use.

According to TechCrunch, Mastadon says it has "gained 123,562 new users as of October 27, 2022 and now has 528,607 active users on the network as of October 31, 2022."'
