SiliconBeat points to Wink, a new search engine that allows you to search for “tagged” content.
Wink lets you…
develop your favorite sites from within Wink and outside of it. Within Wink, you mark favorite pages by clicking on a star beside a search result, and then adding a subject “tag” of your choice.
Or, if you are a del.icio.us user, you can sync your del.icio.us bookmarks into Wink, which will also help guide your searches. Likewise, you can choose to make sure any favorites you mark at Wink are stored to your del.icio.us bookmarks.
