The replacement suggestion is only bad because it's too long, and it's still better than what's there. "Torvalds interview on community, kernel development, & more" would be a way better headline.

The quality of a headline has nothing to do with attention-grabbiness; it's a good headline if I can read it and know whether I'm interested in the contents. To optimize for attention-grabbiness over helpfulness is to defect in the HN posting game.
