Substrate is the messy, guilt-free workshop. LinkedIn is the shop window.

• LinkedIn is increasingly a professional shop window for me: I know who I'm talking to, and that inevitably shapes what I write.
• I want Substrate to be the opposite: technical stuff, half-formed ideas, things I'm unsure about, and the occasional rant into my phone.
• Some ideas will go nowhere. Some will get sharper through writing, arguing with AI, or someone else picking at them. That's fine.
• Occasionally one becomes useful enough to carry across to LinkedIn, Weighbridge, or actual consulting work.
• You don't put everything from the workshop in the window. But you need somewhere to make the things that eventually go there.
