From the looks of it, a lot of people are moving their
short form public group chats to something other than
Twitter. Lots of reasons for this, cascading from the
$44 billion transaction that led to a change of control
at the site.
There have been online mass exodus movements before.
New management by Yahoo after a $1.1 billion acquisition
of Tumblr in 2013 had Tumblr users flee en masse to
WordPress, taking their blogs with them. By 2019, Automattic -
the makers of WordPress - acquired the site for a reported mere
$3 million.
Similarly, the Yahoo purchase of the del.icio.us in 2005
for less than $30 million caused a great number of users
to move their bookmarks to the competing Pinboard site,
and Pinboard ultimately acquired the remaining husk of
del.icio.us in 2017.
When America Online opened up access to Usenet News in
September 1993, the "Eternal September" era of Usenet
started, with newsgroups being overrun by clueless newbies
with no understanding of or interest in the social norms
of that system.
This brings us out of the past to the present day, when
Twitter users are casting about for somewhere new to go.
One destination is group chat sites like Discord. You
gather up all your friends, recruit some others, and talk
amongst yourselves on a multichannel system that's members
only.
A second option is to join one of the many sites that
makes up Mastodon, a federated network of sites that
interchange traffic using the ActivityPub protocol. Mastodon
sites have seen a sharp uptick in traffic from Twitter
refugees.
Because Mastodon is federated, you can join the network
nearly anywhere and have a mostly similar experience. There
are, however, a lot of differences between Mastodon sites, and
your choice of a main server actually makes a difference. The
biggest and most popular Mastodon sites are currently straining
under load and will be slow and laggy. The little ones are harder
to fund, but many of them have active moderation and a strong
topical theme. On these sites reading the "local" feed of all posts
generated by users of the server will be much closer to on topic
for a single topic.
Twitter is staring at a series of crisis conditions at the moment,
with rumors of impending mass layoffs, a pause in spending from
some advertisers, and a whole pile of uncertainty over its future.
There are lots of possible outcomes from this turmoil, but past
history suggests strongly that the new Twitter under new management
will cause many of its most valuable readers, contributors, and
advertisers to change their focus of attention away from the site
onto something new.
