My experience on the internet suggests that high-signal information usually has very low memetic fitness. All the good sources of information I've found have been buried away and I've come across them serendipitously.
Not particularly surprising though, entertainment is the lowest common denominator so it's much easier for that kind of stuff to spread. High-signal information is the complete opposite: very few people can actually tell if it's valuable, and it's not particularly shareable.
To be fair, most people aren't really looking for super high-signal info anyway. Closer to the minimal amount of information I need, presented in an easily digestible way, or looking for infotainment around something they're interested in!
