Companies like Reddit and twitter (and former similar companies like digg) forget that they outsource most of their innovation to external developers who try new things, and some concepts really take off. Their future competition were literally working for them - until they cut them out with paywalls and bad terms. Normally once big enough, they just buy these innovative companies.
They also forget the value often isn’t their network site, it’s the networks that branch off from those networks that hold the real value. It isn’t a subreddit itself, it’s the custom bots they make, the discord or telegram channel meetings and chats, the people who meet up in real life, the external discovery of content, etc. Walled gardens, forcing official apps, expensive APIs, excessive moderation/censorship, etc are last ditch failed attempts to add or create value from a fleeting flock.
Put simply, the above puts your company into a survival death spiral - where you hope you can capitalise enough and quickly - or pivot, before a majority of future paying users churn, and you’re left with some fancy trademark and collapsed revenue. A ghost town.
Given the above, it’s easier to see how Nostr solves these issues. Devs can’t be locked out. Users can’t be banned. Devs actually work collaboratively to grow Nostr across diverse products and use cases, communities can easily splinter and co-exist on specific or a diverse relay set. Discovery will improve and enable greater personalisation. Types of communication will expand and become more seamless.
