"If you force yet another custom, badly-implemented, weirdly-behaving, not-entirely-thought-through scrollbar on me, I will hate you and never visit your website again."

Pretty sure Gmail uses custom scrollbars and I wouldn't be surprised if it's the most commonly used e-mail in the world.

I think Facebook also uses a custom scrollbar on their activity feed.

Same with Rdio's web app and Spotify's web app (unless it looks different on PC?)

IMO that's in spite of their scollbars, not due to them.

It does. It's pretty obnoxious, but they're at least well-implemented, unlike most custom scrollbars.

It doesn't (or at least it doesn't in Safari; maybe it does in other browsers?)
