I used to make things in MS paint that were either topical and in response to the discussion or I'd jut make random characters and see how they play. But I think I grew out of it. Not to say it's juvenile but just because I don't have the energy because I've been focusing my creative energy on books I've been writing.

I try and contribute thoughtful responses to threads here, but a lot of them are "how do you feel about X" and too low effort and open ended to generate much discussion. I offered some insights from Herodotus in the Babylon thread but that talk teetered out in a day.

One pitfall, I think, is to try and force imageboards to be like when we were teenagers and we had time to kill one Paint and Photoshop projects and our senses of humor were a bit more stupid and it was easier to entertain each other. We can allow the board to grow with us if we share thoughts we have during the day. Things are on our minds, I'm sure, but we rarely unload those things here.
