> git blame tells you nothing about the skillset it takes to be successful at any large tech company at a senior level

100%. I don't care who has "scope" or "impact" or is "senior". I want to sit next to the developer I can ask about the pro/cons of any web development framework, that can help me analyze a heap dump, or explain why some transitive dependency is getting pulled in at compile time.

These are the ones I'm successful finding with git blame. They're the ones that can help me get stuff done.
