I am sort of starting to wonder where he's from. Clever to post he's from UK, which of course could be across the pond here but otoh maybe not, and maybe it stands for UnKnown.
Meanwhile we may increasingly think he's an earthbound spambot or data-harvester in training, but maybe he's just a bored national service draftee from the galaxy next door. If so, then he'll be back, but you're probably right in that he won't return to this thread. Between making thread posts, he has to phone home, check his orbit, realign assorted solar panels used to maintain power in his Earth Survey Module and so forth. No time to post replies before time to post next new thread!
Weird if his natural language is write-only. His launch supervisor must have set up his MacRumors ID for him?
I stayed up until 6 am once in college over a weekend. Just to see how it would feel to see the sun rise. I'm the kind of person that just needs sleep...
6 a.m. - reparing my Windows '98. (In "some" other cases it was even later/earlier, when I was busy enough not look at the watch)
4 days - finishing my master's degree diploma, typing footnotes in Cyrillic on a 25 years old typewriter.
