We must ask ourselves if this evaluation is simply a result of the kinds of participants likely to come forward. Typically females at a young age are socialised through 'bedroom culture' and it is a general theme that they adopt literacy skills faster than males. Due to this there are simply more female blog writers than there are male blog writers. Could this mean that because blogging would come more naturally to women than to men, most male blog writers must already have a sufficient background in literacy to want to blog at all - meaning they would be more likely to explore abstract vocabulary?
I doubt this train of thought has much influence on the study at all and this is a fascinating article nonetheless.
