I case you haven't heard, Scott Hanselman recently announced that he is joining Microsoft as a Program Manager in DevDiv, and Jesse Liberty joined Microsoft at the beginning of the month as a Senior Program Manager in the Silverlight group.
Sometimes, I feel as though I'm one of the "Last of the Mohicans". But in reality, it is really just a natural changing of the guard. There will be new bloggers/authors/notables to replace those that join the ranks of Microsoft. Since I joined the blogging craze way back in 2003, a number of my friends from the community have gone on to work work Microsoft (Kirk Allen Evans, Dimitre Novatchev, Christophe Schitko, Steve Maine, and on and on), and some have left Microsoft (Rob Howard, Alex Barnett, etc.). It is just a natural progression. If you have not noticed, over the last year or so I found a new (at least to me) wave of high quality Microsoft tech bloggers (Dave Laribee, Dustin Campbell, Steve Eichert, etc.)
Congrats to both Jesse and Scott!
