Diigo allows you to mark up the web

Diigo (pronounced as “dee’go”) allows you to add highlights and sticky notes on any web page you read.  Think of a giant transparency overlaying on top of all the web pages. You can write on the transparency as you wish, as private notes or public comments. And you can read public comments on the transparency left by other readers of the same page, and hear their “two cents” and interact with them. Essentially, Diigo overlays a Web 2.0 skin on top of the entire web and makes the entire web into a writable, and even more participatory / interactive media.

When you need to forward some web pages to friends, and colleagues,  instead of the whole page, you can highlight specific paragraphs and forward the annotated pages. You also get other cool features such as full-text search of all your bookmarks, notes,  subscriptions to bookmarks by your friends or people with common interests.
