Hacker News Reader

Seems like the typical "pre-Plus" Google project: limited usefulness, but interesting from an engineering standpoint.

Noticed that it still contains share buttons for two defunct Google services: Google Buzz and Google Reader

This was one of the many projects that got gutted by Plus, I'm surprised that it's still being hosted at all.

It's also using dygraphs javascript visualizations for the timeseries instead of Google Charts.
