Same brother. Still using Reddit from time to time though but wouldn't touch Xitter with even a pair of pliers.
It's true that Lemmy doesn't have the same magnitude of content as Reddit but I'm trying to cut down on the doom scrolling so it's a good thing for me personally.
That'll come over time. Reddit didn't start with all those diverse groups either. It was mostly tech based stuff with some news sprinkled in initially.
