Fair point and you could accuse me of hypocrisy since I'll be out supporting with one of the parties this weekend. But I do think that most BG contenders move on, I for one am pretty unlikely to try and tackle the whole thing ever again. I also think that the interest in the story of the BG is about the contender and not so much the history of the event, and in this way it's never over!
Don't worry too much about the BG - I think that interest will probably fade away a bit over time, it's just peaking at the moment what with the book and all.
