Google: Service or Timebomb?

Whether you realize it or not, a revolution is happening right now. 50 years from now, entire sections of history books will be dedicated to the information revolution which began with the birth of the web. Google has played a key role in triggering this revolution by striving to provide searches for not only web pages, but anything else containing information. Here is Google's official mission statement:

Google's mission is to organize the world's information and make it universally accessible and useful.

I am a big fan of Google. Gmail is by far my favorite email system, and I am signed up for just about every other google service they provide. As far as search and web applications go, it's hard to find anyone who does a better job than Google, which is why so many people use their services. They have earned their massive user base by providing innovative products for free, and have forced other companies like Yahoo! and Microsoft to reconsider how they do business. They have done so, for the most part, in a respectful and non-manipulative fashion.

With so much information being fed to Google's computer systems, (as well as Microsoft's and Yahoo's) how will these companies manage their increasing power? 15 years from now, every major book, movie, song, magazine, newspaper, and public record will be indexed by a few major search companies. Even the article you are reading right now is hosted on a Google computer. Placing this much informational power behind the trigger of one company is alarming to say the least, and could lead to an atomic political timebomb. With great power comes great responsiblitiy, but will the CEOs and future decision makers have the integrity to resist taking advantage of their overwhelming power? What if a CEO dies, and the company is usurped by the evil board member who has been waiting for his breakthrough into unrighteous dominion? Uh oh...

In the meantime, I'll continue to use my gmail account and check my schedule on my google calendar. I'll keep using blogger to write Double Stamp, and even manage some of my important financial information with their online spreadsheets. I just hope that we can figure out a way to prevent these companies from snagging us like a crocodile snags an unexpecting wildabeast drinking from a desert pool.

Introduction to Web Feeds

Have you seen the terms “RSS“, “XML“, “Atom” and “Web Feeds” on your favorite internet sites, but have no clue what they mean? Maybe you wonder what these little icons mean?

This is a brief, non-technical tutorial on what these terms mean and how they can save you a ton of time.


In a nutshell, “web feeds” provide users of the internet a way to check newly posted content to a website without having to visit each of the sites individually. “XML” is the format in which web feeds are written, but the details are for the programmers. “RSS” and “Atom” are simply different specifications as to how the feed is written. Sound too geeky? Don’t worry about the details, read on…


Let’s say, for example, that you tend to visit three websites daily: doublestamp, usatoday.com, and reuters.com. Each of these sites are constantly updating their content, so to find out about new articles, you need to check each of them individually, right? Wrong!


If the websites you visit provide a web feed, you can simply subscribe to the feed by copying the URL of the feed into a “feed reader.” That’s what those little icons are for; they are the link to the site’s feed. A feed reader takes the feeds from all of the different websites that you have subscribed to, and displays them conveniently together. The new items that you have not read yet are usually highlighted in bold, or are marked somehow as new so that you don’t need to browse through old content. To see what I mean, look at the following picture of a popular online feed reader by Google. Notice the feeds to the left, and the content to the right.

So, after subscribing to a feed, one can quickly browse through new content on dozens of websites in a fraction of the time that it would take to visit them individually. If you are interested in a certain topic, you can click the feed item and it will take you to the website to read the full article. You’ll never miss an article that your interested in, and you’ll save tons of time.


It is important to make sure that your feed reader will read both “Atom” and “RSS” formats. Some websites provide RSS, others Atom, and some provide both. To help you out, here is a list of some FREE feed readers that you can start using immediately.



  • Google Reader - An online reader that is easy to use. Works with most browsers and operating systems. This one is my favorite.

  • Sage - A great extension to the Firefox browser for reading feeds.

  • FeedReader - A good feed reader for windows.

  • NewsGator - NewsGator is available in both an online version and an installable program. The installable version isn’t free.

  • There are many other readers that you can find by searching the web, and most new browsers have feed reading capabilities themselves.


Give it a try. It’s a simple concept, but it will enable you to browse a lot of content in no time at all. You can start by subscribing to the Double Stamp feed right here:
