One wonders whether it's something he mentioned because so many folk find fishing to be mundane (read boring) and never take it up (their loss, I say!) - or, was it because the topic of fishing is one of the things "on his mind" because of redesigns coming to the profession?
Or, is it simply because he's a marine biologist (well, he's not a marine biologist now, of course, he's lead systems designer, but you know what I mean).
I suspect some changes coming the way of us fisher-folk, my only sincere prayer to the devs is - please make it relaxing... I don't want to feel like I'm having to be a "twitchy" player in order to fish - there are some of us who play the game and, well, let's just say we're not spring chickens any more, and we like to unwind with some simply right clickyness on a bobber now and again :)
