So apparently as of 10:16PM on May 13, 2013 EST the last page of stories, sorted by first posted date is this.
The oldest readable story is here.
And the oldest completed story is here.
I just think it's neat to see where this site went from to where it is now. Though I must admit I am confused by the last page of stories as the "first story" by that has a story id of #18026 magically enough. Maybe it's some weird glitch or something. Whatever.
In any case, YAY FIMFICTION! You're almost at 4000 archived pages of stories!
