I am coding my own hacked together bookmarks manager. I can save any page with a click of the button using SingleFile (a fantastic Chrome extension, by the way!).

Then a cronjob runs and puts it into a folder to be processed into a database, which generates a static html index and puts it in my Google Drive.

Then it syncs offline on my chromebook. Which means that without internet, I can put my chromebook in tablet mode and do some nice reading. I've been very pleased so far.
