... what should we do?
As we can see from this excerpt, BMG is slowly dying. People don't seem interested enough to even start it and the 21st BMG has little participants.
(even though it hasn't happened in months lol)

I see the following problems and solutions:
Problem: People don't notice BMG.
Solution: Make BMG more often. However this might make the audience have less interest in them.
Solution: Make a room for it. However, "there doesn't need a million rooms for everything" and this makes things more complicated.
Problem: People don't like BMG.
Solution: Make BMG less often. This might make the audience have more interest in them.
Solution: Change BMG into something else. For instance, LYAL, or simply discard it. However CMCs probably seems interesting to many people like me and BMGs encourage CMCs.
