I have absolutely no idea why, but DivShare has decided to be a bit flakey today (and was yesterday, too), which means that links on this here blog aren’t terribly available at the moment.
I can’t tell you when DivShare will make all their links usable again, but I’m guessing that someone, somewhere is working feverishly to correct the problem. In the meantime, may I suggest you:
a) read a book
b) spend time with the family
c) feed some porpoises
d) climb the tallest bush you can find
e) paint your lawn
