I'd love to see more niche promotional threads... As in "advertise your fantasy comic here" or "show us your romance story", or even "do you have a science fiction novel? share it here!" When I browse these threads most of the comics don't really get my attention because they don't strike me as somehting I'd look for at that moment, so maybe seeing focused efforts would be more fun than the hundredth "DO YOU HAVE 12.4 FOLLOWERS OR LESS? ADVERTISE HERE!!" , which blend with one another and if it's always the same people posting the same comics and novels, people looking for something new to read might get bored...
What's more, since the focus is on "advertising your story" instead of "find a new story", so many of us would be more inclined to advertise instead of looking for something new to read. Since this forum is already so focused on creators rather than readers, it's an uphill battle, and I'd imagine for a reader the whole forum might be an intimidating place to be XD These threads are fun for finding different perspectives once in a while but I don't really put my hopes on them since the people who see them seek for the same thing as me: exposure.
