Do you have any other good sources? As a marketing guy who wears a lot of hats, it is hard to identify consistent titles that represent what I bring to the table, and PayScale didn't seem to be great, and Glassdoor was hit or miss (in large part due to geographic data despite living in the Bay Area where they should have lots of data).

There is serious information asymmetry between recruiters/employers vs employees, and if information is the best weapon, employees are woefully unequipped to fight that battle.
