Bookmarking systems have been around for years. Yahoo bookmarks, Google Bookmarks, del.icio.us and more along side the bookmarks scattered across various browsers and smartdevices you’ve used over the years. Rather than tying the bookmarks to a webmail provider or a specific computer or device, keeping them in a central spot that can be accessed from anywhere is the best idea. Instapaper collects your web sites for later reading through bookmarklets. A standalone app on iPhone, and integration with many web browsing apps makes this a must. I even use a service like ifttt to move stuff from twitter favorites and google reader starred items into Instapaper, my single place to look for reading articles of interest on my commute.
