Yes, I did not follow the early days of this room too close, but my impression is that you and Ricardo Andrade were the most active here. (And, by extension, probably also in editing and retagging and similar activities on the main.)
Of course, there are other users, too. Stefan Kohl has copy editor badge. Yemon Choi is among users with most edits (currently 2nd).
So maybe keeping this room alive is not completely nonsensical thing to do. It seems that there are users who care about tagging of questions, improving questions, etc.
