Read it Later's paid version has a function that allows you to email links to people so you can share articles and stories, etc. I set up a dedicated Hotmail account, and anything I want to save, I email there. Then I know everything there is a keeper and when I get time, I pull those stories down and archive them in Calibre.

How do you pull the stories down to archive them in Calibre? Are you saving them as HTML files or something similar?

Thanks for the tips on RIL. I'm checking it out now...
