Other uses 
The .st domain is being marketed as a general-use domain, with a number of meanings suggested including the abbreviation of "street", short for "Star Trek" and more. The .st domain is also commonly used to create domain names that spell words ending in st such as "[bur.st]".
The Smalltalk programming language community also has an affiliation with the .st extension referring to the Smalltalk programming language. Both "The World of Smalltalk" (www.world.st) as well as the Seaside (www.seaside.st) web application framework use .st for their domain name.
The state of Styria, in Austria, has ST as its unofficial but common abbreviation. Therefore, the .st extension is used by some small businesses located in Styria, despite Austria's own .at. Also some registrations in South Tyrol, an autonomous, chiefly German-speaking Italian province, use the .st extension to abbreviate the German name of Südtirol in opposition to Italy's .it.
Washington Post URL shortener 
The Washington Post uses .st as part of their domain http://wapo.st. Their .st URL serves as a redirect which they use to lead readers to various articles on their site. This is most useful when the length of a URL counts, such as when tweeting an article. The Economist does the same, under econ.st.
- World.st: The World Of Smalltalk - A collection of Smalltalk-related information
