The new /about page is nice overall. Great work!
However, there's something there that considerably mars the result, and is especially inappropriate on this site.
Various illustrations slide into place. They look like a developer discovered how to do it and decided to show off their newfound trick regardless of whether it was a good idea or not. Très Geocities. Would you like <blink> with that?
The illustrations convey almost no information. The one illustration that does (the answer being marked as accepted) is partly hidden: it's only triggered when you've finished reading the part that it applies to. The illustrations are very sensitive to the window size and scroll rhythm: if your window is too short or too tall and you scroll through it with PgDn, you may not see the animations at all (which is a blessing) or they may trigger while the illustration is only partly visible.
All in all, this is a user interface element that gets into the way of functionality in order to look showy, and that is very brittle with respect to the tool used to access it (maximize your window, get a nonsensical display). This may be appropriate on Apple, but it is the complete antithesis of Unix & Linux.
If you really must keep this animation, at least turn it off on Unix & Linux — it is very off-putting to this site's core audience.
