In May 2005 I started tracking how many emails were still unanswered in my inbox.  As usual, I am very far behind.  Soon after I started also tracking the age of the oldest unanswered emails in my inbox.  That one is even sadder.  For completeness, I added a third grapoh showing the number of emails in my unsorted spam folder.  That is where all the automatically filtered spam is, but I look through it periodically to find items falsly identified as spam.  That seems to be running about 1 in 1000 messages in that older.  Anyway, here are the three graphs.
