Top Web Annotation Tools: Annotate+Bookmark+Collaborate

In case you never came across any ‘Web Annotation’ service before, than basically what it is, is a bookmarking tool (usually in the form of browser addon or bookmarklet) that allows users to annotate (add sticky notes, highlights, etc.) any desired webpage and store it online.

There are many cool things you can do with them, i.e. (1) quickly add sticky-like memos to your bookmarks, (2) bookmark long articles with relevant text being highlighted, (3) store, organize and tag annotated pages online and most importantly (4) share your annotations with friends or project/assignment group members.
