Lol its a metaphor for the type of preaching that involves politics or culture usually. TED Talks are usually in front of an audience on different social issues. They may add some science or sociology and culture. As opposed to grounding preaching in GOds word. They may even rationalise Gods word with social and cultural norms as part of making the bible relevant in todays society.
I think the most famous examples are the TV preacher types. Not too different to a TV presentation with sets and slide shows ect. Maybe an expert speaker on a specific issue. But generally speaking it seems more aligned with how secular society approaches social issues. More about persuation and salesmenship than the gospel.
Strive to be memorable, but let God and his Word change lives.
