I'm apathetic, but please let's not start the trend of self-aware "downvote me" or "why the downvotes?" comments on this website. I'm of the opinion that it's needless, manipulative clutter.
I agree that the former is clutter, but the latter is good, as long as the commenter is clearly trying to learn from/correct whatever mistake they had made. e.g. "This is being downvoted and I don't understand why. Could someone please explain the problem?" or "Why the downvotes? Is it because ...?"
I guess I prefer the fire-and-forget approach, only going back to edit my own comments for spelling and grammar ("EDIT: ... EDIT 2: ... is sort of grating to me). You make a good point though, and I don't believe that comment-self-awareness is universally an attempt at manipulation.
I'll actually upvote you, because I agree this is great. With the 3.3 release almost through the door, 3.x becomes a simply better Python than 2.x and time is ripe to start switching.
Heck, I don't even use Django. But I'm in the lucky position of having been able to switch to Python 3 already (some of my code still has to keep compatibility with 2.6/2.7, which is reasonably doable, but much of it even gets to care about nothing but 3), and I'm happier now than I was on Python 2 - it's a better language now. I'm frustrated about having to defend that view to people who are frustrated about the transitional pain all the time, so a big milestone toward getting that pain behind us is a cause to celebrate. A Python 3 Django is a big deal both pragmatically for all the great sites using it _and_ psychologically for the Python community.
(Go ahead and downvote me, this comment has absolutely value, yet despite knowing that I'm so happy I still feel compelled to post it. :)
