Personally, I could go for less 'cool' on HN and more clarity and accuracy instead.

'Show HN: roll.io plays youtube videos searching list of text. Useful?'

That aside, neat app. It's a clever tagline though.

For this particular link I'm not sure I would have clicked it with the text you suggest. And I'm glad I did click it. But I agree that in the general case, titles on HN should be accurate rather than catchy.

No need to. We prefer quality over wordiness.
