And what’s the deal with the URL’s, NRO? This one has as its useful data “MzcwNmQ4MTczNzBkN2NjNTdhMWQ3MjY2Nzc3NzZhODI”. That’s enough space for roughly 3×1085 posts. (That is, 44 characters on a 52 symbol alphabet, so 4452.) Probably the result of some big ugly hash. 352 bits.
Okay, it’s good to plan for expansion, but if they used a date-time-sequence code they could have an arbitrary number of posts, not a mere 30 trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion.
