I just got back from vacation and I am told that the SaaS architecture guidance site on MSDN http://msdn.microsoft.com/architecture/saas just went live.
This confirm my long standing theory that things tend to happen faster when I am away and the corollary that I should take more vacations J
More seriously, make sure you bookmark it or subscribe to it (yes there is a RSS feed) http://msdn.microsoft.com/architecture/saas/rss.xml
Bonus feature: a picture of Fred with a glowing background (must be due to his great Karma)
As usual feedback welcome.
