Intelligently automatically retrieve data from web that's not sorted, and offer "fields" to sort by. Similar to "translate.google.com" this scrapes a website, and then runs some filters on it.
Examples: There are websites that give you information about software, but they don't sort or filter by price. You don't need the original website to do that for you anymore. From now on you could "googleSort" the page.
