Just realized you don’t have to subscribe to a feed in Google Reader to share something you find on the Internet. Under “Your Stuff” they added “Notes” a while back. On that page there’s a bookmark you can drag to the bookmark toolbar, click it, add a note and share the note in your Shared items. Highlight text on the page and it will prepopulate the description field with it. If you can’t see my shared items, send me a chat invitation in Gmail; pretty sure that’s the only way to become “friends” in Google Reader. Added a test note of a chart from Ross Perot’s perotcharts.com.
