Lemmy can have its fair share of echo chamber syndrome. For example, almost nobody here vocally likes Reddit, and if you post anything pro-Reddit, it's likely to be met with a lot of negativity. I'm anti-Reddit too, for the record, but it's good to acknowledge tribalism even when you agree with the tribe. But the nice part is Lemmy can't have competing echo chambers nearly as easily as Reddit can because we're so much smaller.
