All your points about the site design and anachronisms were accurate. Close to every single user here, long term or new, already had the view and agrees with you. There is no need for or appreciation of redundancy on the topic. You said something everyone here knows and you did it as a brand new user who hasn’t taken in any of the culture or contributed to the site. So basically you crashed a party and ordered everyone to change the music and start cleaning up. You got a bad reception. Quelle surprise. It wasn’t personal. How could it be? No one here knows you yet.

What there is a need for is volunteer developers who might do something about the situation. The problem there is the code base is difficult. Probably so difficult that a complete rewrite is all that makes sense; my view. I’ve volunteered a couple of times to participate if it’s done with a modern framework. It’s not going to happen. Too much work versus too few resources. And there is a fundamental conflict of views among some users. Some think in purely utilitarian terms and don’t care about the appearance at all since it’s just about Perl.

What you might be interested in is some of the customization that is possible currently; Re: Pretify the site with CSS? is a start. I’m not sure it represents the current state of the art. I use it, or some version of it. Makes the site look much better (to me).
