If twitter works for you then that's great, but if[0] you're purely seeking inspiration for creating a startup, you could consider listening to podcasts like Indie Hackers instead. It's probably way less of an attention black hole, but still inspirational.

Appreciate the podcast suggestion. It's more about immersion than it is one specific thing. In addition to the social media angle, I am hopeful tech meetups come back in earnest in San Francisco at different startups; this is the melting pot of ideas and innovation and they're so much fun.
