PluralSight

PluralSight was founded by KeithBrown, FritzOnion, AaronSkonnard, and Bill Williams shortly after the assets of DevelopMentor were acquired by Educational Experiences, Inc.

PluralSight does high-end training and content on the Microsoft platform and hosts blogs and wikis for various folks who work on or with that platform, including TimEwald, DonBox, and HerbSutter.
