Coming to that, you are probably the only author of which I've read almost all published stories, in two fandoms. But at the time, I didn't feel "proper" to comment the work of well-known authors. It sounded a little presumptuous to me. In the same way, when I recced stories in crack_van, I preferentially chose those which I thought could have escaped the attention of many readers. I'm afraid my comments on line were quite rare though I entertained some private conversations by mail when I had specific questions to ask. And when I started reading with a Kindle, I tended to quickly lose tracks of the sources.
