I don't know what Jon was alluding to, which leads me to one of two conclusions:
1) It's a personal matter which is well-known enough that he felt the need to make public thanks, or
2) I'm a jerk, and have completely missed something.
Note that a combination of numbers one and two is not out of the question.
If it's completely #2 -- and there won't be any stepping-on-toes going on -- I'd like to know what it is, and if there's any way that I, as a lowly LWN subscriber, might be able to offer assistance. I've come to grow quite fond of LWN over the years, and that most definitely includes its staff. If, however, it's a private matter, then please just add my "Jon rocks, and I hope everything goes better!" onto the pile.
