> There's some redundancy; topics aren't being combined uniformly. For example, today has the story about Facebook killing 115 accounts in two separate batches

Yes, the topic aggregation algorithm is not completely fine tuned as of now. (See prion's comment above https://news.ycombinator.com/item?id=18359975). It has false positives (combining news stories that really don't belong together) as well as false negatives (not combining news stories that belong together).

We are working on fine tuning the algorithm every day based on incoming news stories. If you stick around, you'll see a gradual improvement.

Thank you as always for your detailed feedback. It's not everyday that one has the privilege to interact with a greybeard.
