Mark Pilgrim speaks the truth about this hype going on with the new announcements of proprietary/vendor specific web stacks and runtimes (Microsoft Silverlight, Adobe Apollo, etc).  Don't get fooled again!:

"Y’all have fun. Play with your vendor-specific runtimes. Don’t call me when you wake up one morning with a pink line in the round window and your BFF vendor won’t return your calls. If you need me (but of course you won’t), I’ll be holed up in my drab unpainted toolshed around the corner, quietly building applications on the web that works."

Love it.
