Keeping it to one puzzle per LTPFer, although my shortlist ended up without double-ups rather organically:
[Doriana] Who spends NYE on Wikipedia anyway? - Intriguing statement with a simple, unguessable and satisfying answer
[Traveller] Coffee and (lack of) politeness - A classic phrasing full of conflict and intrigue, and some clever lateral logic in the solution
[Bardificer] It sparks joy - A paradoxical statement with a lateral twist I hadn't seen before, and a sweet story to boot
[Balin] Ars longa, vita brevis - This wins my award for the most 'classic' puzzle, the one that reads most like it had been sneakily lifted from one of Paul&Des' books
[gendervoid_killua] 3, 2, 1, takeoff! - A simple question and answer, which fit each other well but in a way that is initially counter-intuitive
[JenBurdoo] Accidentally Accurate - A straightforward-sounding question which is nonetheless pregnant with misdirection - and, as ever, I learned something
[Sarisberie] Stumblebum - A lateral catch I've seen used a few times, but posed in such a way my mind didn't leap to it - and such a fun premise
Trebor's 'Ahead: uncleaned plasmasol" was my favourite title.
GalFisk's 'Sand' had my favourite puzzle wording.
