I've never noticed a title being rewritten automatically when posting an article. Are you sure that's really a thing?

There are some auto rewrite rules. Off the top of my head: numbers in the beginning are stripped, [pdf] or [video] can be added to the end, and one more I can't remember that gets stripped off beginning and can cause confusion.

A pdf link to "5 Reasons To Do Things" will be "Reasons To Do Things [pdf]" for example.

„How“ at the beginning is stripped, leading to all these strange sounding „I <verb>“ submissions.

There was also an interesting article on assistive technology called "How Disabled People Use the Web", or something similar, which looked very silly with the "How" stripped.

Yes. And the algorithm is really incredibly stupid, but dang is opposed to even small improvements (like showing the changed title on submission beforehand, like the „x characters to long“ message).

Fixed

So, suprassing 80k karma, one gets title edit rights?

I think anybody can edit a title within a short time of posting something. Or if there is a karma threshold it is way less than 80k.

I caught that one manually but YOShInOn's tail end needs some love and could be updated so it that it fixes up titles that get mashed automatically or adds a comment sometimes to editorialize or provide an archive link.
