I do a bit of this, but I think, what the heck, it’s my blog, no-one is forced to read it – so I do post my personal diary / “hold that thought” type entries for my own future consumption / organisation. Who knows someone else might find it interesting. I have this know the man, know the work outlook too. The narciposts probably say something about the poster, whatever the post says to the poster or the reader. The medium is the message ‘n’all that.
