There are probably some people who don't know what an aggregator is. It's a feed reader, or a program that reads the news feeds from your favorite web site. This is how you can keep up with the news on all the important blogs like Sandwalk!
I use the Goggle Reader that's featured in the following video by commoncraft. It will teach you all you need to know about Really Simple Syndication (RSS). There are other readers that are just as good but I like the web based readers 'cause I can access them from several different computers.
[Hat Tip: Shelley Batts who used to read blogs the old fashioned way.]
There are two types of Internet users, those that use RSS and those that don't. This video is for the people who could save time using RSS, but don't know where to start.
