>>1391Sorry for being rude, it was bad timing with the robot thread. (Also I feel like it wasn't the best choice of picture to go with the subject at hand, but that is neither here nor there)
To answer your initial question, there's a tradeoff between increased growth due to advertising in other girl communities and the chaos of growing pains if the newer posters are unfamiliar with imageboards.
As for threads that encourage participation, I wish media were a bit more active, but I can see that the wide variety of interests other people have make it a hit or miss most of the time.
