Reader has always been about sharing your favorite items. One of the more fun things you can do with them is put them on your blog. That way your readers can see what you've been finding interesting, even if you don't have the time to do full posts.
Until now, putting your shared items in your blog required some technical chops, since you needed to copy and paste some code into your template. We'd always wanted to make this easier, so we worked with our friends on the Blogger team. As a result, the entire process now only takes a few clicks for Blogger users*.
All you have to do is click the "Add to Blogger" button on the put a clip on your site page in Reader (found in Settings). Now anytime you share something, your blog's readers will know about it too. It's more fun than a blogroll and always up to date.
* Just to be clear, this only works if you've upgraded to the new version of Blogger. We switched the Reader blog to it a few weeks ago, and it's been working out great (no more waiting for publishing to finish).
