Personally, the look back thing was boring on Facebook, but how interesting it might be for a look back video of your ATRL membership - the most quoted posts, the drags, the praises, the reported/warned posts, the hit threads, the members you message most, the messy avatars.
My Facebook Look Back video made me tear up. I saw photos from 2008/2009. I haven't seem them in ages. I would probably be bawling if I saw an ATRL Look Back video. The posts from 2010 and 2011. My old avatars.
