Fleck allows you to interact with pages on the web just as if it were pages in a magazine. You can save your annotated page for yourself, send it to friends or colleagues or use it in your blog.
You can start using Fleck right now. It's free and what's best: you don't have to install anything on your computer. Try the search box at the top of this page or add Fleck to your browser with a Bookmarklet or Extention.
