Notice the new search box above the blog archive in this page? It allows you to not just search posts on this site but also articles I have linked to and all the link lists on this site. Go ahead, try it. The results are shown at the top of the page (and not in a new search result page) so that you can continue reading the post you want to.
To add the element into your blog, go to Blogger in draft and choose the element from the layout. There is also a poll element you can add to the site. I wish they had that poll element included in the create post pages, so that I can have a small poll running below each of my post asking the readers to rate my posts (on a 5 point scale) with a nice small graph display.
Its built using the AJAX Search API (main page), and is powered by a Linked Custom Search Engine (CSE).
Another WIP, experiment with CSE when I have time!
