Hoover Dam, nominated by Wehwalt and NortyNort, who said it "has taken hold of the American psyche in a way few other engineering works have." The 75th anniversary of its dedication is in September.

Choice of the week: We asked Dabomb87, a director of the featured list process, for his personal choices. "My favorite was 2009 College Football All-America Team – I'm a fan of American football, and the extended lead makes this article interesting; as well, the references make it a valuable resource. Second for me was List of number-one singles from the 1970s (UK) – I had nostalgic memories of old cassette tapes in my parents' house reading through this list and seeing some of my favorite songs (ABBA, especially). Good supplementary text and images, and good use of color in the main table."

Laughing Kookaburra, (author Noodle snacks), the subject described as "one weird bird" by a reviewer. The Signpost can confirm that these birds emit sounds akin to theatrical laughter.
Choice of the week:Raeky, a regular reviewer at featured picture candidates, told The Signpost, "My favorite was the panoramic view of the Great Court of Baalbek temple complex in Lebanon. Panoramas of this size, I believe, are a prime example of how photography makes an article come to life. This one allows the viewer to delve into an area in a way that a simple snapshot can't do." The image appears at the bottom of this page. Raeky has a helpful hint, too: "Readers might be interested in a feature that lets you easily navigate through these large images on almost any connection: interactive flash viewer."
