Much like i2p freenet is very sparse and aside from mp3 download sites and a few neat tech things i see nothing on freenet worth a fuck. The only way you can dig deeper is scraping urls and manually clicking links and at that point im not sure that is a rabbit hole worth going down.

There is a value though in these protocols for decentralized online archival of information for example. So this project the OP is showing can be used with web.archive.org/save/ and archive.is.
