Rather than just returning traditional search results, Powerset reformats data and pages it retrieves from Wikipedia and Freebase based on your search query.
When you click on "Read complete Wikipedia article", Powerset displays the article through their site, with a floating article outline with links to points within the article. This feature can be especially helpful with longer articles.
Another interesting feature of Powerset is that it allows you to search on what you want to know, rather than having to think of relevant keywords.For example, you want to know George Washington's birthday.
With a typical search site, you'd probably search on "george washington" or "george washington birthday" and hope for the best.
With Powerset, instead enter "when was george washington born" and Powerset returns George Washington's birthdate.
Powerset's main page contains several example search queries to help you get started.

While it certainly will not replace traditional search sites, it can nonetheless be a valuable tool.
