Writing to your facebook timeline via feed dialog

I made a little RWW feed dialog app that allows you to write to your own
facebook feed:

https://www.facebook.com/dialog/feed?app_id=368850139864841&link=http://www.w3.org/community/rww/&picture=http://www.w3.org/community/rww/wiki/images/f/fe/Rww-logo-001.jpg&name=ReadWrite
Web
Dialog&caption=Reference%20Implementation&description=Using%20Web%20Standards%20to%20Read%20and%20Write&redirect_uri=
http://facebook.com/

Hopefully I've done it right.  I'm not sure if it needs to be authorized.

The query parameters:

link = a link you want to display
picture = an image
name = Title displayed
caption = a short description displayed
description = a longer description displayed
redirect_url= where to redirect to

Documentation

http://developers.facebook.com/docs/reference/dialogs/

There appear to be 7 dialogs for different uses

News
Pay
Friending
Auth
Add app
Send Message
Send Request (eg used in games)

Perhaps some nice functionality to embrace and extend in some of our RWW
implementations?
