I've read CLRS page-to-page 3 times and doing pretty significant chunk of exercises. It takes on average about 4-8 months with 2 hours each day. I still think the title is accurate, i.e., its just "introduction". These days at work I frequently bump in to algorithms that would be qualified as advanced and CLRS content now looks fairly introductory to me. In fact book hasn't even scratched 10% of the stuff that we use regularly in our work. I think most people active in CS research feel the same way but if you were programmer doing regular LOB or iOS apps then OP's view may feel more closer.
