Just found out about Tildes.net, a content aggregator that looks similar to Reddit and probably works in a similar way as well. The difference, though, is in the whole ethics of the platform and its operations: see their Philosophy for an example.
I think this is a great step forward for the fediverse in general, as I had not seen a service like this anywhere before. The only downside is that it doesn't seem to federate (yet?) unless it uses the tildeverse ID as credentials.
Great job, Tildeverse!
