Hey, just wanted to say I super respect this post. I'm someone who frequently starts things (both solo stuff and collaborations) and then lets them die for various reasons, but I'm bad at actually declaring them dead. I hadn't realized until this moment how much I've let all those orphaned projects eat away at me by keeping them "alive" in my head. I'm taking this as impetus to go say a few words over a number of dead projects. Thank you for that.
The social space and community you're describing are things I want too, and I'm excited to follow along. I build stuff in such a vacuum today, and share so little. I hope we can both figure out where and what ticks those boxes for us, whether your answer is the same as mine or not.
Best of luck!
