"No reasonable employer cares about college credits earned in high school, the age you were when you coded your first website, or what platforms you tech-supported in school, and yet that material consumes more visual weight than the number of years the candidate has doing Rails development."
I think this is a ridiculous statement, but we almost certainly have a different definition of what makes an employer (cough) reasonable.
My priorities in a resume read are passion, then applied intelligence, then experience. The information you're ignoring here is valuable with essentially no additional variables (doesn't matter much where they went to high school, or what the website did). How long someone I don't know paid you to write code in whatever technology is almost useless information to me.
