Personal anecdote doesn't count as a reliable source for Wikipedia purposes.
A published syllabus might count, although on the other hand it might be considered a primary source.
I appreciate Miller's suggestion, but you're right - even a syllabus wouldn't count. (My Wikipedian instincts tell me that if I came across a random article citing a intro course's syllabus as a source of notability or relevance for claims, I would cast a jaundiced eye upon the article indeed.)
For the last few weeks, I have been engaged in a slow motion edit war on the Wikipedia Eliezer Yudkowsky article, about including discussion of HP:MoR. The specific text being removed, to my eyes, well-sourced and germane to the article. But it may be that only 2 reviews of it is not enough and the other editor will respite if I can add in another RS or two.
Of course, I don't know of any besides the ones I have. That's where you all come in. What can I add to bolster the case for inclusion?
(If this seems trivial to you, I will note that the WP article gets around 2000 readers a month, and will continue to do so indefinitely; the WP article is also ranked #3-4 in Google for "Eliezer Yudkowsky". My impression is also that people reading WP articles tend to be 'high-quality' visitors, who spend time reading it and whose opinions are molded by it. At least, I've noticed this with Evangelion articles - points and quotes I've spent time referencing and highlighting tend to show up in reviews and other mainstream coverage...)
