I'm pretty old school, having messed with computer machines pre-tubes. As a result I have developed a large number of habits that have served me well. One of the most tenacious is the habit of cleaning out my various files when they are no longer of any use to me. (This is the result of saving computing and storage space in "the olden days".)
I purge my history file daily, monitor the available disk space weekly, and banish random cookies on a regular basis.
While exploring, today, I tried to eliminate a couple of diarists that I had "hot linked" over the years. I started with Barack Obama, who last left a diary here in 2006. When I clicked on delete the stupid system froze on Ping.chartbeat.net, and, for all I know may still be sitting there spinning it's wheels.
If "delete" is an option, perhaps the item selected should, in fact, go away?
