I wrote this post for Edudemic and, after 10 days or so, on the principle of waste not, want not, I posted it here with this hostage to fortune, by way of a prologue
Originally written for Edudemic this piece turned out to be an opinion piece that would probably sit ill amongst their upbeat edtech.
But it seems I'm too impatient for words. Checking my stats I noticed rather a lot of visits from... you guessed... Edudemic. Since, when you submit your work you agree that the post will not appear elsewhere, I thought I'd better take it down. You can of course read it
