After an intense google-fu workout session ending in failure I may be the only person in the word interested in doing this but here goes…

Use Google Reader? Want an RSS feed of only unread item? Then hears how!

The secret is subtraction, you need to take your reading-list feed and remove all items with a read tag.

As an example here’s what the reading-list and read feed url’s should look like

http://www.google.com/reader/atom/user/YOURUSERIDGOESHERE/state/com.google/reading-list
http://www.google.com/reader/atom/user/YOURUSERIDGOESHERE/state/com.google/read

Too find out your user ID go to reader.google.com and then enter this line of javascript into the address bar
javascript:prompt("User ID", _USER_ID);void(0); you should then get a popup with your ID

So to get the unread feed you put it all together like this

http://www.google.com/reader/atom/user/YOURUSERIDGOESHERE/state/com.google/reading-list?&xt=user/YOURUSERIDGOESHERE/state/com.google/read

So now I’ve got the Vista RSS Feed gadget (running on XP just to be awkward) displaying a list of my unread items.

Yay!
