I just scrubbed through your blog (jeez! XD) and got stuck somewhere in 2 months ago on the Harry Potter drawing from memory post on both steemit and busy.org, but looking on steemd showed everything going back to account creation, so you haven't lost anything (and shouldn't have considering how this thing is supposed to work!).
I'm going to take a wild stab in the dark guess and say the script is truncating after a certain point so it doesn't kill the browser with unresponsive script errors that could happen if the continuous scroll page goes on forever.
Perhaps steemit et al needs to implement a normal pager for people who want to go back to inception XD
