For a couple of months now I've been following Nurse K at her blog (Crass-Pollination).
Today my Dashboard showed me a new entry at the blog which looks interesting, but whenever I click on the link I get a "This blog is open to invited readers only" message.
UPDATE: By way of Dr Grumpy - seems that Nurse K is taking another hiatus to work through some dramas. "Wishing you all the best Nurse K, you're missed!".
