As previous comments have said, it depends how you want to situate yourself in the online world. And who you want your audience to be.

I’m all for keeping things simple. Using words like’ construct’ & ‘postmodern’ means something to me because I am an educator, but it is very surprising the number of people who do not know what these words and concepts are. Even ‘reflective practice’ is new to some. Eg would your undergrad students know what you’re talking about? Or would it put them off? Or do you care – are you really pitching your blog at fellow educators?
