Like with all social media - it's as bad as you make it.

I've never had much of an issue with Twitter's recommendation algorithms. I find they do a pretty good job of showing me content I'm actually interested in. I did get an influx of political content during the owner switch, but either they fixed that on their end or it quickly figured out that I'm not interested. I'm getting none anymore. Like literally zero.

Lemmy would be equally unusable without heavy curating and content filters.
