I do spend a lot of time on RYM though, especially at work (I sometimes check it out at home but only really write reviews and make lists while I'm working- SF tech life bro).
I see Olson comment on John's FB page every once in awhile but aren't FB friends w/ him myself (don't really have a problem with him but he and I were never really "Babble buddies"). I do miss Jersh though- dude was funny, weird and had interesting taste. Pretty sure he has kids though so it's not surprising that he went MIA. And speaking of MIA due to fatherhood, I hit up AH on FB a few days ago to make sure he and his family are ok (since he's been gone from Babble, FB and IG for like a month or 2 with no notification) but haven't heard back yet.
