I do a daily check on Wikipedia’s Recent Death’s link. I started doing this frequently and then daily from mid 2009 onwards when it seemed that lots of famous people were dying. Unfortunately that has continued onto 2011 and I always check to see if someone I like/admire/know is on the list. But on the 23rd, yesterday, they made a slight mistake in noting the death of Henk Pleket twice in the same date.
