You come across substantial news or blog articles that you want to read, but don’t have time at the moment.
You need something to read while sitting on a bus, waiting in a line, or bored in front of a computer.
This is perfect for someone like me. My bookmarks are completely out of hand; I often scrape articles I want to read and when I most want to read them I am away from my computer.
My only fear is quickly bumping up against storage limits (both in space and time span). Here's hoping this site takes off.
