To be honest, I'll side with Yorick here. There was no reason to ask the question in the first place, though it was perfectly fine to do so. Simply choosing whether to list the extra books or not would have sufficed without hurting the topic, and Yorick's original response to him wasn't offensive in any way, if a bit sarcastic even. I don't think he was being a jerk at all until people called him out; I honestly would have gotten upset too.
Now, I wouldn't have said morfowt was being an 'idiot,' but he did ask for an answer to a question, so he was inviting the response.
Anyway, back on topic:
The buffahuman book was just kind of random and pointless, like a lot of books in that epoch of the series. Personally, I don't rate it low because I hate it, but because it just isn't important or interesting in the grand scheme of the series. Plus its plot involves the presence of Helmacron technology, which means it was definitely intended as filler in the first place.
