A question

I've noticed that some of my posts get no response at all, while others get lots of comments. To give two examples, NOBODY responded to my post about Green Knowe. And those books are, in my opinion, really beautiful - possibly among the best fantasies ever written, and I'd be happy to talk about them. No one responded to the clip of Michelle Paver and the wolves. And that, too, is a very well-written series, in which the teen protagonists grow in believable ways. I had one response to the news that Megan Whalen Turner's fourth Attolia book is actually coming out. Then I put up a post about how unhappy I am with Harry Potter these days, and suddenly there's an intense discussion about Snape and his character going on. Okay, it's true, I love Snape. But at this point, two years after the last book, no one's mind is going to be changed about him. At least, I don't think so.

Is it the case that people visit here only for my posts on Snape? Just wondering.
