Since your site is down I can't see how it's organized, but I would think hard about having two separate parts to it. One would be a site that changes slowly, perhaps a descriptive page, maybe with a 'best of' or examples that you cull. Then have the main page that is rapidly updated and keep the 'bots out of that. There's no reason to index the rapidly changing map, is there? Just index a slowly changing pointer to it.
