Marker.to is a Chrome and Firefox extension that allows you highlight text on a webpage and share that highlighted section with others. Once installed it is very easy to use Marker.to. To use Marker.to just click the marker icon whenever you’re viewing a page that has text you want to share with others. Then highlight the text, choose a highlighting color if you want (yellow is the default), and Marker.to will provide a unique url that will direct others to the content you’ve highlighted. You can share that url via email, Facebook, or Twitter.

Applications for Education
Marker.to reminds me a bit of Bounce which also allows you to highlight and share parts of webpages. In both cases the tools can be useful for directing students’ attention to a particular passage that you want them all to read on a website.
