In the OS/2 2.x days my primary means of interacting with other OS/2 folks was the Canopus (Wil Zachman) forum on Compuserve (75060,264 checking in). Weird that I still remember my Comuserve user id!
At that time, there was a somewhat common saying "Annoy IBM, support OS/2!". This was essentially mocking the ineptness (disdain?) of IBM marketing for OS/2.
