When I first learned what an aggregator was, I immediately thought of Pinterest just because it is something that I use on a daily basis. If you are unfamiliar with the site, it is a virtual, online board to which people “pin” things. Has there ever been anything you have seen online that you loved and didn’t want to forget? That’s the main idea behind Pinterest. It can be very inspirational, but also extremely addicting. You can visit other people’s boards, or simply search for a specific thing.
