Would you pay for a custom search engine and RSS feed?

Idea: Personalized news feed and web search. You tell us which sites you want to monitor. We'll:

1. Give you an RSS-style feed of their newest content, as well as any content updates.
2. A search engine that exclusively searches your sites.
3. An AI-driven calendar that recognizes dates in the content of those sites and suggests events for you.

Use cases:

1. Monitor your competition. Anything they post on their site, you'll know about.
2. Stay on top of your industry. Pipe in industry publications to follow them all.
3. Specialized knowledge database. Your search engine only searches the sources you tell it to, so you won't have to weed out all the nonsense.
4. Follow people, brands, and publications you care about. Be the most informed person in your world.
