Link feed update - I found a bug!

[andrewducker]

Turns out that if Delicious goes down then it think there was no links, and carries on to the next day. D'oh! That'll be fixed presently...

Edit: No, wait, it looks like Delicious was returning empty RSS feeds while it was down. Nice one guys. Not that I can check, but I can't see any way that would have happened other than empty feeds being returned. *sigh*
