A todo list that helps me figure out WTF to do, maybe by generating checklists from a corpus of facts, sources trusted via web of trust, social collaboration, etc.<p>I&#x27;d input &quot;trip to Thailand&quot; and the service would break that down into:<p>1 check your vaccines<p>1.1 hepatitis A most important<p>1.2 try local clinic X, click here to dial<p>2 check your insurance<p>2.1 click here if you have home insurance<p>2.2 click here to purchase trip-specific travel insurance<p>3 decide dates<p>3.1 week? two weeks? month? click to specify<p>3.2 pick a flight, click to browse curated list<p>And so on. (These should probably be in reverse order but I&#x27;m too lazy to change the numbers.)
