It was more recent for me, in 07 I read moneyball and I started reading this site actually. I then read baseball between the numbers and ever since then I stopped even paying attention to how many RBI's a guy has and his batting average. There are still some advanced stats that I don't understand but that's mostly because I haven't taken the time to look too closely at them. I'm still stunned though that there are people who use the old school traditional stats to evaluate players but at the same time it does seem that a lot of people are at least starting to consider stats like OBP and OPS, and while they are still flawed stats it's still nice to see.
