To me, the term ‘blogosphere’ sounds dumber than ‘academic,’ even if you didn’t know the meaning of either term.
Say them both out loud.
I’d prefer “the ungated, free entry, merit-driven, competitive, methodologically eclectic, wisdom of crowds-based global hive mind,” vs. “ivory tower, methodologically dogmatic, elitest, academic world where you either data mine to publish empirical papers or invent endless permutations of theoretical models.”
