Ask HN: Is pragmatic marketing useful?

A few PM colleagues have had high praise for the pragmatic marketing courses. Others seem to have never heard or cared about it. Is the curriculum useful? Is it fluffy? I feel like I'm looking at a lot of buzzwords.

Specifically, is it applicable in the start-up space or for larger tech companies or both or neither?

Does anyone have other product management resources they recommend for these contexts?
