I think topics that are interesting or fun and have an open question where people can share their opinions get more attention.
My most popular topic was one about "extreme-advertising" comics/novels. In this case it worked a lot because it gave a fun twist to the typical "advertise your comic". by being "EXTREEEEEEEEME"
Other popular topics i got:
-Draw your OC with our oposite hand"
-So, you can sub to your own comic and put likes on them⌠¿Opinions?
-Which fictional characters scared you as a kid?(or still scare you?)
-Let`s learn from each other mistakes!
-The no context game is back!
They were either games/challenges and/or open questions where readers could elaborate.
Saw some of your topics and the quizzes you shared were fun, but lacked the "open question" factor.
