One of the most interesting aspects of selling your widget is seeing how other people use your product and what their requirements are.   dAISy was originally built for ship-geeks that are entertained for hours with MarineTraffic (like myself). I also broke out a few pins for tinkerers that want to connect dAISy to other widgets (again, like myself). Turns out, the majority of my customers are boat owners (unlike myself).   Boaters use dAISy to keep track of ships around them for navigation
