But except for other techies (fellow students in comsci/comp. eng), I ran into very few people who ever used VLC. They just put up with WMP/VLC/iTunes.
Now with Netflix/Amazon/iTunes, I've found myself rarely ever needing another video player. Not that these commercial entities are "better" than what VLC offers, they're just easy enough and provide enough content that I no longer feel the "need" to go to VLC...but that's also because I'm older and have less time to watch things overall.
