sharing buttons

i would love a button on the toolbar like you get with iphoto and aperture so you can share a page by email, or post to wordpress, stuff like that

Have you tried using OS X’s Services for this? E-mail wouldn’t be a problem. You could just select the text you want and use a Service to send it to Mail. WordPress would probably require some program that (a) does that sort of thing and (b) has a Service for it. MarsEdit would be a likely candidate. Also note that Scrivener has some special copy modes in the Edit/Copy Special/ sub-menu for grabbing the current selection as HTML, which is very handy for blogging.
