On the other, so? What audience exactly do you think I'm doing the History of Bibliographies of Bibliographies for? Or Selections from Early Middle English: 1130-1250?
But the PG-TEI crowd isn't talking about writing items of academic interest into TEI. They are talking about taking books of general public interest, which have already been written by caring volunteers in HTML, throwing away the HTML, and forcing everyone to work with PG-TEI, whether they like it or not. When all that really needs to happen is a half-dozen lines of CSS needs to be "tweaked." And which probably could be "tweaked" automatically if Marcello's tool for example was on top of its game. If you want to work an old English text in TEI or something for a doctoral thesis, and then donate that to PG, then do so. Just don't make the rest of us follow suit.
