Instapaper

Instapaper is a bookmarking service that allows web content to be saved so it can be “read later” on a different device, such as an e-reader, smartphone, or tablet. Create notes, highlights and read Ad free! Plus you can email or tweet the info directly to others, great stuff.

Bookmarking apps have been around forever and were one of the first big things on browsers, then between phones, etc. Instapaper is that, but its focus is cleanliness and readability. When targeted adds are everywhere, Instapaper removes them and cleans them up. The big plus for teachers is: you can save classroom articles, then print them off, without subjecting yourself or your students to all the junk on the website, and you don’t have to do anything but click save, since it’s a browser extension. Beautiful!
