The idea of and value of 'exposure' has been debated since the early days of blogging.
I could call up entries from my blog in 2001/2002.
The feeling, amongst those of us who felt like blogging pioneers, was that by opening up we shared our common humanity and in many respects become less lonely souls as a result (not that I didn't need additional companionship being happily married to my soul mate with two small children at the time!). The press picked this up as scandalous and novel.
This kind of blog is a genre in its own right amongst the thousands of genres on 120 million + blogs.
I question any need for us learners to 'open up' in this respect. Indeed for most of the last module I 'hid'behind an image of an MRI scan (something I might return to). I see no need to reveal who I am, my face, age or gender. In this environment what counts (or can be discounted) are these words.
In terms of our relationship with the tutor, I would expect in a Summer School, or if attending the Oxbridge style one-to-one Tutorial, that a relationship could/might form.
Indeed, attending by father-in-law's 70th and then 80th and even his 85th I've been impressed by the 100s of former students who turn up. Some guy.
I don't think (their names already escape me) want me as a friend, or a friend for life ... though as a colleague for sure.
