I just had my first day at ESRI today, where I have joined the ArcGIS Server .NET ADF team.
Everything here seemed well-prepared and set-up when I got there, including a small "seminar" for everyone who started as ESRI today, and ready-installed desktop and laptop computers.
I already got to look "under the hood" of AGS and play around with it - there's definitely some very cool stuff in there! Hopefully I'll get some time to blog some more about it later - or you can have a look at Arts blog as well.
