I'm sure it's very easy to forget where you originally got half your stuff from. I know I got about 10 different emails containing long lists of Helenisms both during and after the show. There are also loads of web-sites that have a core 15 or so. So as an idea, I don't think it's realistic for there to become a single source.
Some lists are definitely better than others and those that create them thoughtfully should be praised. Being an obsessive it annoyed me most when some people had obviously taken to exaggerating some of them. In particular "Dove's a bird innit" was often changed to "What is a dove?"
At least these ones are reasonably accurate.
