They recently added a very cool new feature; the site memory button. Download and add it to your website and visitors can easily save your content for later reading. Evernote makes it simple to install on your site; there are specific instructions for Tumblr and WordPress and if you know a little HTML, you can specify the particular part of the page you want the reader to be able to clip by entering the div tag in their online form.
Download Evernote here (free) and look for the green Remember icon to start saving posts and clips from your favorite sites.
