Ask HN: Is there a demand for Bookmarking app that does more than bookmarking

I constantly find myself bookmarking interesting things only to forget about them and rarely coming back to them.

What I am thinking is, I build a product that: - Let's you bookmark to the cloud

- Finds related interesting bookmarks other people have and suggests to you

- Makes bookmarks searchable by keyword, url etc

- Periodically scans your history and mentions your previous bookmarks related to the subject. Also, suggests from your previous bookmarks if they are related to the page you are currently viewing

- sends you daily emails with interesting bookmarks which are relevant for you.

Wondering if this is only something I find useful or if there are others who need this. The way it's different from pinboard is it constantly scans what you are doing and suggests relevant content. Also reminds you everyday to look at your things you left off.
