Mastodon isn't a Twitter clone but it was made to fill that exact niche. Short posts with mentions, hashtags, and URLs. Such details give the feel of a platform. The velocity, the atmosphere. On a personal level that's just what I like. And I think it would be reasonable to assume many of those who signed up do, too.
A social network is also a kind of common playground. Individuals have the capacity to spoil it for others. For example, when there was a bug in Mastodon that allowed you to make links spin, many made use of it for fun, which spoiled the experience for people with motion sickness. The more vectors there are for how information is transmitted, the more pronounced this is.
Right now, there is not a whole lot of ways that individual posts can escape their boundaries to affect the whole experience. They can use lots of line breaks or a wall of text, but it's limited by a maximum height. They can use caps, but they don't stand out that much. Custom emoji are one of the weaker spots when people use them as fonts, and that's annoying.
But adding more elements to the mix? More control over visuals? People WILL make it look ugly, that's a guarantee.
@kai Are you not reading the thread you are responding to?
@Gargron the PR was not a "full spectrum." It was a fixed set of formats - incoming only. Definitely not a big deal, but nice to have. I think you are blowing this way out of proportion.
@kai I'd say 168 comments were blowing it out of proportions--besides, of course once those things could be displayed, the authoring wouldn't be far behind. Glitch-soc already added it and it is part of the discussion now.
@Gargron I'm not talking about comments; I'm talking about the PR.
@kai Anything that touches CSS is a big deal for me.
@Gargron fair enough. All you have to do is explain that to people.
