Nostr has really proved to already be so much better than Reddit. On Reddit, you can get banned from speaking in certain "communities" just by saying/doing something that the individuals (not professionals - not even close) do not like.

Then you realize something like Nostr exists - a place where someone cannot suppress you. You are free to speak as you would like and engage with the people you want to engage with. 

Seems like revolutionary technology [somewhat simple at the same time - great for growth] to me. How long until this method of Social Media is widely used over Reddit, Twitter, Instagram, etc? 

 I guess as long as these platforms are earning money by displaying ads they will never implement decentralization tech.

They depend on paying companies which want to be in charge when it comes to situations like "displaying our ad next to inappropriate user content".
