Edit: I've massively edited the below. The original comment was angry and well, that serves nobody.
Why would you make this comment? Someone took the time to create a niche piece of artwork, that you would have to be in the know in order to appreciate fully. Of course you don't think it's interesting, as of yet you've used this site solely as a way to prosthelytize your blog. You are not the intended audience.
It would be like me commenting on a post titled, Xiaomi Mi5 Specification And Price Got Confirmed: No More Rumors and saying, "Not at all interesting." -Which, for me would be absolutely accurate, but I'm not the intended audience and therefore, it would serve nobody by my writing that. It would just be me being a dick.
