Ask HN: Idea Validation- Content Summarizer

Would you be interested in a service that summarizes content from sites that you frequently visit?

Personally, I follow several RSS feeds and I feel like I would be better served reading summaries of the content rather than the content itself for many of the feeds.

Extending the concept to video, I know I would find value in being able to read a summary of a given TED talk rather than having to watch a 15-30min video.

Does anybody else feel this way?
