The only thing I'm worried about is whether or not I'll get to hear Geoffrey say "It's PeepCode!" again. That's kinda become a hypnotic trigger to my brain to start learning over this years.
Other than that, I've been a happy subscriber to PluralSight going on a year now probably and a credit addict at PeepCode for years. One thing I've always wished about PluralSight was that it covered open source topics as timely and nuanced as it does .NET topics, and one thing I've always wished about PeepCode was that it plowed through it's old 'Upcoming' list a lot faster. This move at least seems like a perfect match and so I'm very happy for both sides and to be a customer.
