Came here when the Reddit 3rd party app threat started looming, loved it and never went back.
Sure, Lemmy doesn't have the same variety and amount of content that's on Reddit but that's because it's a smaller and newer platform along with the fact that not all instances federate with each other (which is great).
I still get my scrolling urge fulfilled and presented with random memes and news that I'm interested in without the data harvesting factor which is perfect for me.
