What is nice to see is that the front end is in Perl. I can't speak for the back end. Given the direction a lot of companies are taking (.NET, Java etc) its good to see Perl still being taken seriously.

I agree, it's great to see a big corporation using open source technology and giving back to the community at the same time. It's a shame there's as yet, no perl success story about the BBC.
