There seems to be PPS blogs popping up all over the place. One that caught my eye recently was that of Aurelien Koppel, a Paris-based BI consultant. Aurelian blogs in French, something I know will bring a tear to the eye of both Bruno Aziza, a Frenchman, and Adrian Downes, a French-Canadian. For those who studied or are familiar with the language this will present a way to stay up to date on the latest in the PPS world and dust off your long-lost French skills. If, however, you define 'language' skills as fluency in C#, C++ and VB check out the Windows Live translator tool which does a pretty good job at converting the entire blog in one hit and displaying the side-by-side results.
Did you study German instead of French at school? Well you're in luck. MS Press released a book on PPS Planning written in German: Unternehmensplanung mit Microsoft Office PerformancePoint Server 2007.
