Bluesky raised venture capital specifically to avoid the ad-based models that create toxic engagement loops on other platforms. This financial runway allows them to observe monetization experiments within their third-party ecosystem, aiming for a future model that rewards creators first, rather than prioritizing advertiser demands.

Bluesky is using AI not for content generation, but to democratize development. Its tool, Addy, allows any user to create custom feeds or moderation filters by describing what they want in plain English. This empowers community-led experiences without requiring any coding knowledge.

Substack's founder doesn't see it as replacing other social networks but as a distinct "city" with a unique culture—intellectual and cosmopolitan. This framing attracts a specific type of user and creator, differentiating it from "cities" like TikTok or Twitter.

Major tech successes often emerge from iterating on an initial concept. Twitter evolved from the podcasting app Odeo, and Instagram from the check-in app Burbn. This shows that the act of building is a discovery process for the winning idea, which is rarely the first one.

Bluesky is building an open social graph to prevent what Facebook did when it closed its API, which killed innovative apps like Hinge's original "friends-of-friends" feature. This open approach allows any developer to build new social experiences on existing connections, aiming to unlock a new wave of creativity.

Bluesky's COO reframes its perceived left-leaning user base as a circumstantial outcome of who first left X, not a flaw. This mirrors the early days of other networks (Twitter for tech, Reddit for gamers) and is presented as a common, temporary growth phase before the platform diversifies into broader communities.

A key tension observed is that a platform's technical design often fails to predict its eventual community culture. Bluesky, despite its utopian, decentralized architecture for openness, has still developed social toxicity and "mobbing," showing that human social dynamics frequently override architectural intentions.

Wabi allows users to create and remix personal "mini-apps" that can only be used within its platform. By keeping the content (the apps) self-contained, it aims to build a social graph and network effect around software creation and consumption, analogous to how YouTube became the central hub for user-generated video.

The next generation of social networks will be fundamentally different, built around the creation of functional software and AI models, not just media. The status game will shift from who has the best content to who can build the most useful or interesting tools for the community.
