Presumably you understand what I'm saying ("he's 'just a vain postdoc on an ego trip'"). Of course I know what his professional status is, it's the most prominent information on his website.

It's a shame that rather than actually considering the very evident pathology here (i.e. the production of mediocre vanity blog content that serves primarily to improve the author's profile) everyone is either downvoting or nitpicking.

You might have better luck if you were to expound upon the ways in which you found the content to be mediocre and how it might be improved rather than personally attacking the author for what you perceive his motives to be.

OTOH he might just be writing for the pleasure of it and getting self-feedback from it (the more you explain something the better you understand it).

I mean, if you know what his professional status is, why say that he's a postdoc when he isn't?
