January 2015- moot creates the board and has his final Q and A with the community. Deluge of shitposts. It's worth noting that /qa/ never had a board link in the list.
Very Early to Early 2015- the shitposters grow bored and head back to their original boards.
The community that is left was those with nostalgia or just a genuine love of the history of 4chan. This was the original golden age of /qa/, so good that the users organized and even convinced the staff to keep it. (or they just didn't care) The "happenings" thread started at this time, a place where people share links and content from their board and talk about them in a friendly manner.
Early 2015 to Mid 2015- The [s4s] spam wave era. The old community was almost entirely driven off by a constant flood of extremely low quality threads and posts from [s4s] over the course of months. Things became so bad that [s4s] created entire images in the catalog from 60+ empty threads at a time. Some people still maintained their commitment to the community and created good threads about 4chan, fun, and the internet in general, but it was clear that /qa/was never going to be the same.
Mid 2015 to October 2015- [s4s] spam started getting deleted. Board is on the road to recovery. Until…
October 2015-Hiro arrives, with a link on the blotter to his upcoming Q and A on /qa/. Deluge of shitposts as general 4chan users are once again made aware of the board. The community tries desperately to maintain the old threads, but it was hopeless and the community once again broken. The board stays practically unusable for a few months. Some people on /qa/ seem to like hiro while others are very distrustful towards him. Over time hiro seems to lose most of these fans.
