What echo chamber? 33,000+ npubs can currently openly interact through my Nostur WoT, which is up by 2000 since a few weeks ago as my follows and their follows increase, and I can easily see any of the others outside it as I choose. “As I choose” is the key here.  

 Imagine having to follow someone so they have a voice on a social network 

 

 You can toggle it on and off 

 Does your fix work on any relay? 

 Seems like you just don't like that people can have different opinions about which solution is best for them. If so, you are in the wrong place! Check out mastodon. 

 By the way, i did both (i have a wot relay, a have a relay where i filtered out the spammers, and a i have a relay where i enforce NIP13 difficulty). I can choose what i want to see at any time by just switching relays. pretty cool, huh? 

 How does that work? The nip13 relay I mean? What’s considered proof of work to be able to write 

 Just like the NIP13 says: you need to "mine" an id for the note that starts with as many zeroes as the difficulty you set. In the relay i just check if the number of zeros matches the mined difficulty.
