What I have noticed this week since the release of Harry Potter and the Half-Blood Prince is how many people are walking around reading it, with it poking out from their bags, with it sitting on their desks -- pretty much everyone is reading it. Which means pretty much everyone is reading (if you subscribe to the a+b=c theory). And that, to me, is very exciting.
I am about half-way through it and am rationing how much I read on a daily basis because I don't want it to end too quickly - tempted as I am to just finish it.
For this little game I am playing with myself, I give me an 8 out of 10 on the Geek-o-Metre.
