How do I remove all shared items from Google Reader?

Question

My shared items feed was private, and I want to make it public, so I decided to remove all it contains.

How can I do this?

Answer 1

Unfortunately, there still isn't a way to bulk unshare items in Google Reader.

The solution offered is to use keyboard shortcuts to make it a bit easier.

While viewing your shared items

1. Press shift+s to unshare the item
2. Press j or k to move to the next or previous item
3. Return to step 1; Repeat as necessary

I expect you could use something like AutoHotkey to automate this further.

Note: Since the Google Reader change to utilize Google+, this is no longer possible.
