Lol. Reddit hasn't been leftist in a long time if it ever really was. There were some leftist spaces, and I guess a lot of users were left-of-center, but the platform certainly wasn't.

I came over here when they blocked third party apps. I didn't join earlier because I thought it'd be similar to Voat, which was apparently horrible and an alt-right cesspool. I was pleasantly surprised. I like that people can have actual discussions here without things being flooded by thousands of comments.

Also, since you're new, I'd recommend against Lemmy.world. They're a little aggressive with moderation. They're the largest instance, which is another reason to go somewhere else. The fediverse works best when no one instance controls it.
