It's taken just under 3 months, but I see that someone finally noticed that the change to the viewport rotation default. For a while there, I was beginning to suspect that finally, after so many years of endless, heated debates filled with personal attacks trotting out well worn battle lines like the blasted blackbirds patrolling our garden do everyday, that finally we'd see some peace when this change occurred.
Hope started to blossom that perhaps those who had been campaigning for it for years would finally be able to down the banners and be able to get onto some serious work in comfort; that some of the "opponents of all change" would actually discover that this works better for them in many (though perhaps admittedly not all) scenarios (but really, there isn't such a thing as one-size-fits-all optimality anywhere for anything, so bleh!); and that seasoned users who already had strong preferences for one over the other were happily coping and moving on as they always do.
Personally, it would be one less setting to tweak on any foreign Blender install/setup, and I'm sure many converting users would also agree. No more queasy and disorientating view rotations when doing a "run with factory defaults" to check out some bug reports... yay!
Alas, it appears that we still had to have yet another flare up. A vocal minority has taken it upon itself to view even the slightest comment as an offensive attack laden with inaccuracies ripe for criticising, correction, and "you-are-an-idiot-if-you-don't-do-this" evangelism, all the while ignoring the polite requests of moderators and other sensible and respectable members of the community trying to diffuse yet another incarnation of the religious flamewar dead in its tracks. (It's interesting also that the traditional post-release flamewars this time are playing out on "local" turf instead of the "global" arena, which in some ways is a pleasant change, at least from a PR perspective).
