I recently started using Pocket (formerly Read It Later) as a replacement for my browser favs and web sessions saver so that i can access them from any browser/computer.
The service is nicely designed with a simple UI, search bar, different views (List/Thumbnails), you can add tags, and filter articles by tag. It comes with a Chrome extension or a bookmarklet to save your tabs to Pocket and an Androïd/iPhone App well integrated.
BUT after looking through the site, and searched the web for a way to import my 450+ favs, it turned out there is no way to add multiple links at once for the moment.
Anyway, i decided to create my own importer hacking a bit the bookmarklet and here it is: Massive Pocket Uploader
If you want to have a look at the code it is on my Github.
