Most of these big brand sites have very little of either, especially with their 'multiple domains' - often times nothing in the way of authorship, +1's, or even a face on the site somewhere telling the user who is behind it. No attempts to build trust.
When they have deep pockets. don't you think it is easy for them to build these, if they don't have them already?
