I always marvel in a service that could easily monetize their product or traffic but chooses instead to essentially beg for funds. Or even possibly charge for tiered access to the archives (something I would pay for).
Wholesale 'archiving' (copying) of websites seems like a pretty gray area to play in. Of course, it's ridiculously important that someone does it, too. However, I suspect that a big reason they get away with it is that they're a not-for-profit organization.
Perhaps I'm not bold enough, but I'd be hesitant to try to 'monetize' the simple re-publication of other people's content.
