If you run across a web page you want to share with a friend, don’t send her a link to it — send her the page itself. Just press Command-I and a dialog will appear, asking for the email address of the person you want to send this web page to. Just enter her email address, along with your text message, and click send, and it will send the contents of that page (complete with graphics, formatting, links, etc.) to your friend. She’ll be able to see that page right within her email application.
