Discussion we had this evening. In NYC we are bringing back the IRISH HELLO. AKA THE 90s. Here’s how it works. You and your friends all share location. Sporadically throughout the day (lunch break, coffee walk, after work, before work) you check to see where they are. If you’re close to someone, you just show up at their location. Aka bring them a coffee to work, stop by their apt unannounced, kick shoes off and spill the tea. Spontaneously grab a drink or dinner because you’re in the same vicinity. And even if you’re not, meet in the middle. It’s easy to get around here. We’re nostalgic for a time that does not exist and yet we have the means to create it and still we refuse. Everyone is too cool or too nonchalant or too scared to appear desperate. Who gives a fuck. I think we should all be a little more desperate. You’re alive. You need people and people need you. Be the one who calls. Be the one who makes the plan, who sets the tone. I guarantee you’ll be surprised at who shows up. It’s better to be the person who tries than the person who doesn’t.
HELLO I AM HERE.

Would you rather own x% of a startup that you think has y% chance of success or y% of a startup with x% chance of success? Assume x < y < 5 and "success" magnitude is equivalent
53%Own less, higher chance
47%Own more, lower chance
19 votes • Final resultsIve noticed on avg my female friends are less comfortable accepting generosity from me (paying for group dinner, picking up a gift/grocery/errand) than my male friends. “No you don’t have to” vs “haha thanks let’s run up the tab”. Curious what other people’s experiences are /why?

Prediction markets let you bet on outcomes, but so much more is possible.
This paper introduces Multiverse Finance, which splits the financial system into parallel universes so you can short the market today, but only if your candidate is going to lose the next election.
