I actually want to see a timeline of how long it took for each question. The 4chan posts all have timestamps for when the answers were posted so this shouldn't be too hard to do.

There are archives of the older threads as well.

I watched it live during the last ten or so. Each question was solved within about fifteen minutes. I tried to contribute to the process, but every time I found a clue, someone beat me to posting about it by a minute or so. The power of collective intelligence is amazing.

The last few were pretty easy. We were on beat for the cyphers used, and the last one just happened to be picked up by a music nerd.

Based off when the solutions (or "gotcha" hints) were posted:
