I got to hear a few comments from Tim on the matter at Confluence. He wasn't unpleasant about it but from the sound of things, I wouldn't have blamed him if he had been.
As for Realms of the Gods, that's one I tried to re-read recently and was noting how close to the edge the main character came to Mary-Sue-dom. (Okay, she walked over a few times, too.) But there were some good characters in there.
(Though she killed off my favorite. I've liked stormwings ever since because of him.)
