Marker.to is a simple annotation tool.
Have you ever used a marker pen for highlighting your paper documents?
Marker.to will do the same for webpages! After you install a browser extension or bookmarklet and run Marker simply by clicking on the icon, you can highlight text on a website with your mouse.
Annotating helps to point out important information in long articles. Our annotator creates a special link for the highlighted version of the page (like http://marker.to/XYZ123). You can share it through Twitter, Facebook, e-mail, IM etc. Or just bookmark it with your favorite bookmarking tool, i.e. Delicious.
You can view highlighted page with any browser! No bookmarklet or browser extension is necessary for viewing.
