The mobile version sucks butts, I can't go to the last post on a page it just takes me to the most recent post I've read. For threads more than a few pages long it makes things pretty darn annoying.
Also it does this thing where it has a bar across the page saying the page is loading, sometimes combining two or three of these identical bars that do not go away which makes it impossible to click on shit. I'll try to screencap that next time it annoys me.
