Hmm, I think that's more of a #bugski for their mobile version. I have no trouble when I hit the back button getting back exactly to where I was even if I had hit 'more' a bunch, and I use desktop Firefox. However, on desktop Firefox, my "more" button disappears after a few clicks, so it's not infinite, just kind of gives you a few extra posts. Would be nice to be able to customize how many you see before needing to click the "more" button.
Fun stuff: You can get the creators/admins to see your post by mentioning them, like shouting "Help me Obi-Wamkenobi, you're my only hope!" or looking in a mirror in the dark, twirling around and chanting "insomniasexx, insomniasexx, insomniasexx", or emailing the Vlog brothers and asking them where thenewgreen is.
