Visiting:
I’m seeing the same hangs/unresponsiveness.
I scrolled from the top to post 8 and Chrome’s tab was hanging hard and threw an “Aw, Snap” error in the tab.
I tested in Safari scrolling through from the top got to about post 45 before the tab was locked hard with a mostly white page and a spinner.
I tested in Firefox, and it managed to scroll to the bottom with a lot of jagginess, then it threw a “Warning: unresponsive script” error.
Happened on the iPad/Safari as well.
Can you scroll through that page without a huge JS spike/hang on whatever browser/platform you’re using?
