Assuming you're not simply being facetious, what would that look like?
Some sort of meta-rss feed that delivers a 'best-of' for weekend perusal? Perhaps it could be collated/curated and then printed in a handy offline version for weekend digestion?
1. Look for weak signals (i.e. some random post about some random subject area)
2. Monitor to see whether it gains traction up slowly but surely (i.e. not your typical HN burst algo but something that might be months or years to pick up)
3. Deliver to user before it peaks but after it has reached some momentum.
