Until the release of Yahoo! Query Language, one of the key parts missing from del.icio.us (or "Delicious," as it's now branded) was a full-text search API. Delicious Search Exploder uses YQL, Pipes, and a couple of native feeds from Delicious to provide an on-page search-and-browse experience, for users, tags, and sites.

Here's a toolbar bookmarklet that looks for a MyBlogLog identifier on the page you're on, and uses the MyBlogLog API to dig out information about its reader roll.

The Badger uses Yahoo! Pipes and JavaScript to create Web badges out of any RSS feed. Edit colors, change feeds, pages, and headlines, and pick up your source code at the bottom of the page.

Using the new MyBlogLog API, this mash-up shows each visitor's tags, sites authored, Twitter tweets, Flickr photos, YouTube favorites, Diggs, last.fm tracks, del.icio.us bookmarks, Upcoming events, professional status from LinkedIn, and more.
