For Mormons, What Is 'Radical Orthodoxy'?

Recently, several Latter-day Saint writers got together and wrote a proclamation of sorts that rustled a few feathers. The write up was called, "Latter-day Saint Radical Orthodoxy" and many felt it was either radical or orthodox but not both. Here's what I mean by that, as one of the signatories. For some, the concepts were so clearly good and orthodox that it didn't read as very radical. Yet others felt it was so out there and radical that it was certainly not orthodox. Another opinion voiced was that the manifesto was too hard to understand with the article's healthy helping of vocabulary the average person wasn’t familiar with.
