Awesomehighlighter works like a real highlighter pen, you select text with your cursor (which turns into a yellow marking pen) and the selected text appears with a yellow highlight. When you’re done selecting the text, you can do one of several things:
You can email the selected text, along with a link to the page, to a friend or several friends.
You can share the page link on Twitter, Facebook, WordPress, or Delicious.
You can click “Copy” and paste to your Windows Clipboard so you can email it, add it to your blog, or social networking page.
Firefox users: You can download Awesomehighlighter as a Firefox add-on and take it with you. Internet Explorer and Chrome users can visit http://awesomehighlighter.com/ to use the service.
