Here's a URL to add to the Safari bookmark bar that you can click on to create a new mail message with the URL title as the subject and the URL itself as the body...
Go into the Safari bookmarks window (Cmd-Opt-B), create a new bookmark, title it whatever you want, and add the following as the URL:
javascript:location.href='mailto:?SUBJECT='+document.title+'&BODY='+escape(location.href)
Now when you're at a page of interest, click that link, and mail will create a new message with the URL title as the Subject, and the URL as the body. Good for saving off a few seconds when you're researching info for clients or friends.
