There are some interesting comments to my “languages are languages” post that I wanted to highlight — a disadvantage of blogs is that comments are often the best bit but are subservient to the posts they are on. I also brought the subject up on the PPIG (Psychology of Programming Interest Group) mailing list, again prompting some enlightening discussion.
By the way, PPIG are holding a Work In Progress meeting here in Sheffield from the 18th-19th April. A call for abstracts is out now. Heartily recommended!
