Guten Tag

One more portal, to look for tagged post, bookmarks, photos, even videos and podcasts, is called Guten Tag.
You can sort your search results by source (faster) or by date (slower). Among the services included, there are del.icio.us, blogmarks, flickr, Technorati and many more.
Nice site.
