Im not a fan of most of their search improvements. It seems like Google these days is good at telling me what I already know but have forgotten vs researching and discovering about information I don't know anything about.
Their blog posts about search are kind of the same. Reading anything google tells us about their search algorithm feels like I'm churning through countless iterations of PR spin, rather than actually learning anything new (contrary to, for example, how backblaze blog posts are packed with info).
