Just a reminder that if you are interested in news about the motu proprio to be released any day now, please see this post which is updated daily (scroll and most recent dates will be on top) . It makes sense to me to keep these things together. Also, as far as commentary goes on the old Mass, I respectfully refer you to those who know far more than I. All I can do is give you the convenient link groupings to things I find in my internet travels on the subject.
Also, the last thing I want to do is to saturate everyone with post exclusively around the motu proprio, as historical as this is.
If you are really interested in the motu proprio, I suggest doing what I do, which is to visit Fr. Z's blog daily.
