This evening I had my first Tweet Up ever; it’s not actually a real Tweet Up, because I’ve met fellow vExpert Stuart (vinternals.com) before at the VMworld 2009 in Cannes where we attended the most secret “Virtualization PowerShell community Night” ever. But first let me explain the term Tweet Up; it’s a real world meeting between two or more people who know each other through the online Twitter service. While Stu is traveling trough Germany, I’m delivering a VMware Fast-Track training course in Munich, our tweets crossed and we had a meeting at Stu’s hotel - Le Méridien. I didn’t go unprepared, because I wanted to know everything about the “vSphere 4.0 Quick Start Guide”, since Stu is one of the authors he finally agreed to do a little interview.
