Techmeme mostly has human curation and a little bit of automation, though it is hard to tell from the outside how much that factors in. Human curators also rename article titles to provide a summary of the contents in an attempt to save you a click if you don't want more detailed information.

Isn't the other way around? Mostly algo / automation with a layer or curation? At least that's how I think it used to work, maybe that's changed.

At the very least it seems like the clustering is algorithmic and "most" of the ranking.
