ティッピング・ポイント―いかにして「小さな変化」が「大きな変化」を生み出すか

Gladwell's approach connects small behaviors to big societal trends. I wonder what led him to explore this angle and how he figures out which stories to highlight.

The book covers examples from the 80s and 90s, but I'm curious if readers see these principles applying to today's social media-driven world.

There are so many fascinating stories, but I wonder what guided the selection process and if there were stories that didn't make the cut.
