However, I *did* correct for age (i.e., converted age of user to likely age at college graduation).

Blow's data is based on total users by age whereas yours is based on % of graduating class. So to compare effectively you at least need to know the distribution of the population by age (census has this). Secondly it's not clear if your data is based only on college graduates, which are a small subsection of the population and which also have higher incomes and higher rates of internet connectivity. Still, reversing Blow's chart and overlaying it is pretty cute - I remember college profs doing this with viewfoils (which puts me in the demographic with only a 7% probability of being in a social network ;-) Hey James, you’ve got a bit of an apples v oranges comparison here!
