Tue Feb 22 2000 19:43: Joe Mahoney reminds me that the low-tech version of Slashdot in the pre-Y2K After Y2K! comics was called The Open Sores Newsletter.
Note: I'm not mad at these people. It's just weird and disturbing to make up a joke and then over the next two years see the joke percolate up to appearing in newspaper comic strips like Foxtrot.
I'm fairly sure no one made up the joke before me. I first used it a year before I saw anyone else use it.
