I think it might be simpler to just do it the way the Star Trek EU does and let people choose to integrate or not integrate whichever canon they want.
Well, no. Unlike most of you, I’m a person who actually cares about continuity. I would like Star Wars to be a multimedia project, a single universe made up of multiple media that’s basically consistent with itself and between the various stories, as much as possible. I’m absolutely in favour of the existence of and official continuity, I think it’s necessary. This doesn’t prevent the individual fans to create their own personal Canon, and in fact I am the first to do so. But I think the existence of a stable and consistent official continuity is important.
I understand that as well and I also like that. However, there are things in the old EU that I wouldn’t want to be canon even though they were all integrated somehow. I think everyone always had stuff that they ignored. For me it’s The Old Republic MMO, big chunks of the prequels, everything post New Jedi Order, and loads of cruddy books and comics scattered all over.
