Wow, Google Reader has one absolutely fabulous feature I completely missed: a next bookmarklet, which takes you to the next unread item of your subscriptions when you click it right within your browser.

(Google Reader → Settings → Goodies)

It is particularly useful for subscriptions which only include snippets or when you want to read an article in context.

You also can filter it by tag, so you can mark the feeds you want to read this way with some metatag if you’ve got too many subscriptions.
