As a VSS admin who ripped out VSS and replaced it with Subversion, it's a good thing. Having your VSS experience rendered worthless is something most VSS admins dream of. It stops the stabing pain behind the eyes.
To actually make this post on topic: sometimes advocating a product is just dumb. Especially if it's a bad product, then you're dumb and dangerous. Just like many things in life though, people hate to admit that they're wrong.
