Oh dear: thanks to blogger crashing yesterday, Mrs Angry has lost the last published blogpost, ie Only connect: BT and the cult of Vital Vision.
Mrs Angry is not in a very good mood.
She will endeavour to rewrite the post when she is feeling less irritable.
Update Saturday: Mrs Angry's sanity has been saved by the foresight of a reader, who kept a copy, now reinstated. Many thanks David.
