Will we do experiments like Reddit r/place or The Button here on kbin?
It probably wouldn't work with Lemmy, but kbin users could do it. Might give the fediverse more attention, but it would need to be more original than a r/place clone.
You could maybe make a magazine where each post represents a pixel and you can comment a color to change it then make an app interface that visualises the canvas when you enter the magazine and automatically posts for you when you click a pixel to change its color. That way each instance could take part in the canvas making if they wanted to.
I kind of don't like that idea. I come to KBin for purist Reddit-esque discussions and link sharing, and anything more would just be clutter. As it is, I already ignore the microblog.
