Just catching up after a weekend at a music festival.
1) Yes - same guy.  Have no idea what the personal issue was.  Some guesses but they are just that.  He told me today he hopes he can tell me some day.  I didn't press and offered the various assistance programs we have for employees.  I moved on and let HR handle the separation, comp, return of equipment, etc.  Just asked for a document to transition accounts which he is doing.
2) I'm incoherent in a lot of threads, surprised that just the Tiger Woods thread was mentioned.  Not sure what the posty was referring to though.
3) Call it old school, call it what you will.  There are still some things that should not be done via text, email, etc.  Resigning is one of them.  It's part of leaving the right way, getting references.  Honestly sorta shocked that so many thought it was the norm, no big deal.
