Do you like it when an writer tells you in their book their ideas are cool?

[KingOfChaos]

a) It doesn't tell me much about the product (okay, they're cool, so what?)
b) It tells me too much about the author (why should I care what you think is cool?)
c) If I disagree, I probably won't by the book; whereas if it was the same book, and they didn't say that, but played up it's virtues, I may come to agree in the end. Kind of that the book may convince me that they're cool, but I'm not just going to take the author's word for it.

So a bit bad, but usually I agree, so....

I personally attempt to avoid editorializing in my work at all costs, so this would probably never end up in a Realms of Evil Games book.
