As I go through my livejournal entries adding tags, I've become very fond of news sources of links that have not expired.
The Register is one favourite, the
BBC is another. Other news sources, especially small town newspapers (which of course often have the most interesting and weird stories), don't bother to keep their stories around, or change their addresses so that when you look for them a year or more later, they're gone.
I've had to delete a few entries that contain dead links which I cannot resurrect. Some I've been able to refresh the links with a different, and perhaps more lasting, link to the same story.
As of today I'm mired in January 2007; I hope to have finished attaching tags to every post within a few weeks or so.
