I personally think that this framework is better than what reddit currently has.
For example, a single instance dedicated to programming with its own various communities within it is a lot easier to manage and moderate than having all those communities (aka, subreddits) on the main reddit page itself. The fact that all these individual instances can interact with other instances (or not, if desired) makes this more robust. The fear a lot of people have right now with reddit is that the reddit staff will just kick out all the mods of the popular subreddits, instill mods that will obey them, and essentially perform a corporate overtake of all those individual communities. That doesn’t seem like it would be a problem with lemmy.
I am excited to see how this all plays out long term.
YouTube without an adblocker is such a mess. I wish alternatives like https://odysee.com had more of the content I watch and less Nazi bullshit though. YouTube really needs some strong competition since they have an effective monopoly on long-form videos on the internet. :(
