Flynn was one of the first MPs to use the Internet to communicate with constituents, and in 2000 won the "New Statesman" New Media Award for his website, which was voted the best MP's website on many other occasions. He was an early adopter of "Hansard" CD-ROMs, and wrote a book, "Dragons Led by Poodles", about the devolution campaign in Wales in the 1990s, in which he criticised some of his fellow MPs severely.
