Well actually James Finister has long been in the blogosphere but he has a new blog Core ITSM that I should have mentioned before now. Very useful thoughtful skeptical views on ITIL in particular and ITSM in general. I don't agree with everything he says, which is also a good sign.
I had some small part in the discussion that came up with the name of this blog. Whether James does or not I'm not sure, but I see it having an ideological connection with my own ideas of Core Practice: cut the crap, don't gild the lily, look for the key necessities. If I stay unemployed much longer there will be time to explore that connection!
