I realize that I haven't even described what things I want to influence people on. That's because I'm speaking generally. This can apply to things both big and small. Politics is the most obvious. (I really wish the voters in SF hadn't just voted to expand police budgets and give them more tools to oppress.)
But it's more niche stuff too. Frontend development is in bad shape right now. And so is interviewing for technical roles. I care about a lot of things.
