Gmail This!

I just discovered the awesome bookmark Gmail This. Just drag Gmail This into your bookmarks bar and click it whenever you want to G-mail someone the current website you're visiting. I wish the Gmail This bookmark had Google Reader's bookmark Share This feature where any text you highlight is what users you are sharing with on Google Reader see before they decide they want to view the full website or article. In the case of Gmail This, users would highlight text, click Gmail This and any text highlighted would appear in the G-mail. Another feature that would be nice for Gmail This would be automatically embedding youtube videos or pictures.
