Facebook told The Next Web that it was "piloting a way to highlight notifications you might find most useful," although Lopez notes that the feature (as seen below) highlighted almost all his notifications and is probably a bigger deal for serious Facebook power users. The obvious caveat is that we haven't seen this on our own feeds yet, and Facebook tests new possible features with limited groups all the time. But given that the platform already aggressively curates what you'll see in your feed, notifications are a natural next step — especially as Facebook turns them into a bigger content delivery system.
