@0x0961h @grizeldi Yeah. I think the issue is with the audience of GMTK - I would expect the majority of it being gamedevs, but those have their own projects and less spare time than your average gringo. Plus it was Mark's first game. He didn't have a niche or style players would know and would be eager to have more of.
Screenshot Saturday is very similar. I expect it being followed mainly by other gamedevs and more of a tool for marketing, i view it as a motivation source when gamedevs mutually like and discuss their projects.
So far the best blend of gamedev and marketing that I've seen was with Pascal from Orange Pixel. He balances that line of gamedev content with casual dev updates for his audience. But he spend like 15 years polishing his social presence and it works for him so far.
