I don’t fully understand how lemmy works completely yet. But for example I made an account at Division by zero and subscribe here to post. Is it not just a more inconvenient version of making a reddit account and being able to post practically anywhere?
Also what’s the difference between making an account at one instant and just making one centralized account for the social media?
Pretty much. By splitting the platform into smaller chunks (instances) you reduce the effect any one instance has on the rest of the platform. The price for this is convenience however over time people will find solutions for this.
