The web site description of CoScripter:

CoScripter is a system for recording, automating, and sharing processes performed in a web browser such as printing photos online, requesting a vacation hold for postal mail, or checking bank account information. Instructions for processes are recorded and stored in easy-to-read text here on the CoScripter web site, so anyone can make use of them. If you are having trouble with a web-based process, check to see if someone has written a CoScript for it!

Jon's discussion emphasizes the DSL perspective (and end-user programming).

The community dynamics enabled by exposing a DSL seem to me the interesting aspect of this discussion. Yet another example you can use when arguing in favor of textual, user accessible, DSLs.
