Tech pundit Robert Scoble brings up a couple of good points in an on the subject of Facebook's acquisition.

He uses Highlight, an app similar to Glancee, and calls it "networking for introverts" because if you go over to meet someone that the app suggest to you, it gives you information about what kinds of things he or she likes as well as who you both know. So in that regard, the app helps you have a conversation.

"It also gives social proof for who you are and how you fit into the network," Scoble said.

He also points out that apps like Glancee and Highlight point to a future in which the technology we use increasingly remembers our behavior so as to provide us with richer, more helpful information.

"We're in the homebrew computer society age of these new kinds of serendipitous apps and apps that learn about us," he said.
