For what it's worth, I completely agree with you, for all the reasons you're saying. With talks in particular I think it's seldom about the raw content and ideas presented and more about the ancillary ideas they provoke and inspire, like you're describing.

There is just so much content out there. And context is everything. If the person sharing it had led with some specific ideas or thoughts I might have taken the time to watch and looked for those ideas. But in the context it was received—a quick link with no additional context—I really just wanted the "gist" to know what I was even potentially responding to.

In this case, for me, it was worth it. I can go back and decide if I want to watch it. Your comment has intrigued me so I very well might!
