Offtopic: When I scroll this article in Opera it takes around 2 seconds from start to stop, and it's very jerky, even with smooth-scrolling off. It works perfectly fine in Firefox.
I've noticed it before, especially with long, well-designed pages, which is a shame.
I think I found the problem: the current versions of Opera don't support hardware acceleration.
There is a lab build that uses OpenGL to speed things up, but it only made this page slower. It passes the microsoft fish test with flying colors, though.
