Fair enough, but the content of the abstract itself already had content that was new to me. Actually, the abstract alone was useful for me, as it hadn't occurred to me that feedback might actually be harmful in such an environment. In retrospect it's obvious, but I hadn't happened to think about it.

I often scan through abstracts of scientific articles, only absorbing the information contained in them. Yes it would be better to read the whole articles, but there are too many interesting articles to read them all, and if I ever actually need to check up on the details, I can return to the article in question.
