The letters page in MacWorld (oh, what a thin little book that is these days) had a contributed bookmarklet that improves on the all-but-useless Services -> Mail option.
To use it, create a new bookmark and populate the address field with this (yes, there is a hard return/newline before SUBJECT).
What this will do is create a new mail message, put the title of the page in the Subject, and put the href and any selected text into the body of the message.
Or just drag this to your bookmark bar . . . .
