How to organise speed dating events
If you want to skip the somewhat lengthy event report, head down to the Speed Dating and Poly Organizing section.
This writeup started as a report on a poly speed dating event I have been helping to organize, and turned into a meditation on holding innovative poly events.
I'm not sure exactly what you mean by "counting combinations." Also, you need to keep cultural considerations in mind: probably not everyone who reads this will know what speed dating is.
Try to phrase the problem in a more mathematical way.
A number of countries with dwindling populations desperately want their citizens to have more sex, but Japan is going the extra mile.
Around the country, local Japanese governments have set up speed-dating services where people can come to meet potential lifelong partners.
The programs come in response to the country's population woes.
