FYI, this is almost entirely untrue. Maybe for some old versions of IE, but modern browsers can handle extremely long URIs

Yep, I rechecked it and seems Chrome/Fx/Safari all support at least 32k. I replied in another comment I'm considering a checkbox to allow even longer URLs, though, I don't know who would want to paste them for others to read. :D
