Poor Scott McNealy. The Sun Microsystems ex-CEO and current chairman is the hungry ghost of Silicon Valley, showing up at the odd event and rattling his chains sadly. This time it's tomorrow night's Stirr mixer, guest hosted by CNET's Rafe Needleman. (Incidentally, Needleman himself is pimping his new CNET blog Webware, which at 6 contributors, needs about 7 fewer.) McNealy is there to "talk and take audience questions about entrepreneurship." Sun is pitching in a couple servers for door prizes. A Greek chorus will handle the wailing, gnashing of teeth, and rending of garments to accompany McNealy's oration.
