Right? It's a whole thing! I'm actually writing this from my own app which posts it to my website which posts it to Twitter. You can see all my replies (to twitter and elsewhere) here: aaronparecki.com/replies
Do you happen to know if those reports are from people with dual core machines instead of 4+ cores? I've heard similar complaints about the ATEM Mini and am trying to track this down.

I'm not sure what you mean, indieweb.org/POSSE is a pretty central part of a lot of people's setups as a way to stay connected to the wider social media world.
There are plenty of tools (Adobe, Apple Clips, etc) for creating media outside of social apps.
