1.	I'm subscribed to quite a few sources, and the range of sources is significant. Consider that I get news from the New York Times, the BBC, and from weblogs like Sam Ruby (an expert programmer), Jon Udell (InfoWorld columnist), John Robb (he works with me at UserLand), Mike Chambers (works for Macromedia, writes about Flash), The Shifted Librarian, Ernie the Attorney, analyst Kevin Werbach, Ed Cone (North Carolina columnist), book author Christian Crumlish, my own weblog (Scripting News). I also subscribe to News.Com, The Motley Fool, The Register, Doc Searls, a local newspaper in South Carolina (Go Upstate), O'Reilly's Safari service and Patrick Logan (a developer). I am currently subscribed to 73 feeds, some people I know are subscribed to as many as 300!
2.	The key point is that I don't have to visit each of these sites to find out what's new. My computer, running aggregator software, does it for me, every hour, automatically. The information is formatted in XML, but I am barely aware of that, as with all compelling apps, the technical details are tucked out of the way. Like all open formats, it's easy to figure out what's going on. Here's an example of the XML behind news aggregators.
3.	Not only am I getting news from professional news organizations, but I am also hearing from people and non-news organizations who make a difference to me. Rarely an hour goes by without something interesting happening, my mind is stimulated, I get new ideas, and of course I share them. It's all about choice, customization, and communication. No one has the same virtual newspaper as mine, and mine is changing all the time.
4.	Over the last few months it's been interesting to watch many of the smart people in weblog-land discover the convenience and power of news aggregators. In many ways it feels like aggregators are where weblogs were a couple of years ago, just about to be discovered by a much larger group of people.
