My former role was working with ISVs. ISVs get their own site, http://www.isvinnovation.com/ which contains some great online webcasts. If you are a developer and you are new to Azure Services Platform,then there are five great Webcasts to take a look at.
And one for business decision makers Windows Azure for Technical & Business Decision Makers: Introducing Windows Azure
You will also find some great webcasts on Visual Studio, SQL Server and more. Enjoy.
