Guesstimate – A Spreadsheet for things that aren't certain
I would love to see this idea translated into event planning/calendaring. Probabilistic party planning. I want to see what might be happening tonight in addition to what is definitely happening.<p>"If 5 people show up at my house tomorrow evening, I'll hold a poker night." 10 people were invited and 4 of them RSVP yes and 2 of them RSVP no. It looks like there's a 95% chance I'm holding a poker night tomorrow.<p>"The X team has a monthly meeting on the 1st, never fail. They haven't decided on the location yet, just that it's on the North Side." As the team members pick possible locations, the possible locations appear more distinct until one is chosen.
