I read the "Vampire Diaries" back in high school (around the time when they first came out), and I really enjoyed the series. "Twilight" and the "Vampire Diaries" may look similar on the surface, but they're actually very different. (Then again, I've never read "Twilight," nor plan to. My knowledge of the series comes straight from Wikipedia and other websites.)
Though my tastes in the vampire genre have changed since my high school days, it will be interesting to see what they do with the series.
