not commenting when I find something that doesn't appeal to me. I think even with constructive criticism, less is more

I don't do concrit, even if people ask for it. I like to focus on what I love about a story, not what I don't. I have quite often read books which do nothing for me, but I don't waste time emailing the author. I just give them to charity and move on. The author's vision is theirs and unique to them, and it's not for me to pick it apart. (I would point out obvious typos etc, but that's it).

But yes, when I find some-one writing a character as I envisage them, I gorge on that. I love it.
