Now that we can have Shared Access signatures, the Authorization section seems incomplete. Currently it reads:
http://msdn.microsoft.com/en-us/library/dd179440.aspx "Get Blob"
"If the container's ACL is set to allow anonymous access, any client may call this operation to read the contents of the blob."
http://msdn.microsoft.com/en-us/library/dd179451.aspx "Put Blob"
"Only the account owner may call this operation."
This is a little confusing when the reader is focused on Shared Access Signatures. Please update the documentation to compare anonymous access vs a shared signature:
