I loved kitesurfing on Lake Michigan before I moved out to the gorge this year. I was out in Indiana and usually rode MC, Lake St and Wolf. I made some great friends and have some awesome memories of my time there.
Lake levels are near record high currently, and causing massive amounts of erosion all along the coastline. It's actually quite interesting to watch houses, dunes, roads and other structures fall into the lake as nature does what it does. [0]
Removing a few million gallons a day isn't going to hurt the the lake that much.
For any fixed odd number of friends k you could keep the network consistent by only allowing people to join in groups (call them "cells") of m, where m is even and greater than k.
"Sorry, Gary. Come talk to me when you have 558 friends. Gare? I'm sorry, Gare, those are the rules. Everyone has to be equal. It doesn't matter if you'll never have 558 friends and I only had to find 32. Everyone's equal! Don't you see, Gary! Gary? Gare? What are you doing. Sic semper what? Aughhhh."
