!! 2017/06/17 - Thinking about Mastodon

Some people are describing Mastodon as a decentralised Twitter, but that's
rather misleading.  It's better not to try to understand it like that.

Yes, Mastodon is decentralised, but in some sense it's not a single thing.
Here is a way of thinking about it.

Imagine running your own version of Twitter.  People register with it,
people tweet on it, and everyone can see what everyone says.  After
a while you want to be able to follow just some people, so you set up
the concept of "follow", and have two columns.  The first is for things
you say, and things that are said by the people you follow.  The second
is for a chronological time-line of all the tweets.

Actually, this is now a little different from Twitter, so let's not call them
"tweets", let's call them squeaks.

----
********> width="10%"
********
(Diversion for a little Q'n'A ...)

* If it's *your* version of Twitter, surely only your friends/people
    with similar interests will register, so why would there need to be
    a separate columns for people you follow?

* Any given person has several interests, so perhaps I find that in general
      person A talks about stuff I'm interested in, but person B is, for me, generally
      even more interesting.  So there's the "flood" of all the squeaks, but there is
      also a curated time-line of those squeaks from people I personally know, or
      who are particularly interesting (to me).  Other people on this instance might
      be interested in the same "flood", but have other specific people they want
      to pay more particular attention to.  As the community grows, this will become
      even more important.

* Or is like a regular friends and a favourites column effectively?

* You could think if it like that. But if you want this sort of thing to be popular
      and useful, you do need to allow people other than your immediate friends
      to register.  Their friends might/will also want to join, and you might not
      want to follow them.

* And would I, a regular user, have to register on multiple versions
    and tweet/squeak separately on each of them?

* That's where the "Federation" idea comes in, and that's explained further
      down.

(we now return to your regular programming ...)

So it's going well, but it's quite small.  But actually that's OK, because
you know that people in general don't say anything interesting.  More, your
instance of this Bird-thing replacement has a good community feel, and most
of the people on it have quite a lot in common.

However, you notice that there are other people also running the same
software that you are, and some people on *those* instances are saying
some interesting things.  But not all of them.  So what you do is create the
facility for people on your instance to follow people on other instances.
Anything said by people "over there" followed by people here are copied
here into that third column.  So the third column has the squeaks of people
in other places, provided there is a reason to believe they might be
interesting.  That reason is given by someone here following them.

(Another diversion ...)

* So this is like when Twitter tells me a bunch of people I follow
    are all tweeting about the same thing or have all liked a picture
    or something?

* Not really, no.  This is where you get to see the things other people
      on this instance think are interesting.  This gives you the possibility of
      discovering other people on other instances, people who are effectively
      implicitly recommended by the people in your community.

(... and we're back!)

OK, so the obvious question is: Why is this better than Twitter?

There are several reasons.

Firstly, it's open source, and not controlled by a company that has to make
money from it.  As a result, no ads.  Further, the fact that it's got many, many
instances means that if one starts to use ads, people will probably migrate
to another.

----
********> width="10%"
********
  * Are the 'instances' visible to one another?
    (Obvious problems of discovering one's community if not.)

* That's a good question.  Currently I'm following people who boost
      tweets from others, so I end up following people on other instances
      because of toots I've seen.

********<
----

Secondly, it's distributed, in the sense that there are now dozens of
instances, so if one dies it only affects the people who were on it.  There
is nothing stopping instances from dying, but one would expect that over
time some will prove to be long lasting and robust.  I also expect that
very soon now there will be tools for exporting your data in a form that
can be re-imported into another instance.  I expect people will regularly
backup their data - it might even be automated - and then if an instance
dies they can move.

Thirdly, if an instance is "acquired" by a company, the same migration tools
will let people move off it to another, so that removes the incentive for a
company to buy an instance and drive it according to principles people
don't like.  Funding so far is personal - some of the admins have patreon
accounts, and users are donating.

Fourthly, Twitter has been messing about with how replies work, and with
messing up the chronological nature of the stream.  Mastodon is as far
as possible adhering to the time-line.  It's unlikely that a new Twitter
front-end could fix this, as Twitter has been pretty aggressive about
shutting down systems/tools that don't adhere to what twitter wants in
the way of presentation.  More recently, people are becoming reluctant
to write things to work with the Twitter system because the big T is
changing things that break third-party systems.

Of course, this might not be the Twitter killer, but Mastodon has been
gaining users quickly over the past few weeks, very quickly in the
past week, and it may have gained critical mass among techies. If so,
it may be made accessible for non-techies, and then we can see what
might happen.

Twitter might not die, but the more sensible people might move to Mastodon
and leave the screaming rabble behind.  The idea of Mastodon being
small communities that cross-connect in a limited way might prevent
the big ball of mud that Twitter has become.  Perhaps a little like local
social clubs which are part of an umbrella organisation.  There are already
external tools to cross-post between Twitter and Mastodon, they may increase
and become accessible to civilians, which will help the migration.

The fear is that if/when Mastodon gets any kind of wider exposure, the
screaming rabble will come.  That may be true, so it may be that we will
have to rely on strong moderation on small instances.

Only time will tell.  What is certain is that it's still growing.
