Social Media BrandsIn my recent blog about dangers of social media I made reference to my IT work over the last twenty years. It wasn’t until after the blog was published that the significance of the time span hit me like a 2 x 4. Twenty years! How many of us remember that the first website was created only 20 years ago in December.

How did I pick that topic at this time? Was my subconscious directing me write on the subject because of the anniversary? Serendipity? Some unter-geek, genetic, internal clock awakening my limbic brain? I don’t know.

How interesting then to see a far more prescient, but related article by Sir Tim Berners-Lee, inventor of the World Wide Web, just published by Scientific American Magazine on the web: Long Live the Web: A Call for Continued Open Standards and Neutrality

Berners-Lee assails the corporatization of the web, governmental threats to freedom of speech, and the `walled garden’ approach to social media sites.

The Web as we know it, however, is being threatened in different ways. Some of its most successful inhabitants have begun to chip away at its principles. Large social-networking sites are walling off information posted by their users from the rest of the Web. Wireless Internet providers are being tempted to slow traffic to sites with which they have not made deals. Governments—totalitarian and democratic alike—are monitoring people’s online habits, endangering important human rights.

He remains hopeful that OUR internet can be saved from itself and draws a line in the sand.

As long as the web’s basic principles are upheld, its ongoing evolution is not in the hands of any one person or organization—neither mine nor anyone else’s. If we can preserve the principles, the Web promises some fantastic future capabilities.   …

The goal of the Web is to serve humanity. We build it now so that those who come to it later will be able to create things that we cannot ourselves imagine.

Hello, My Name is URL

Once upon a time websites didn’t exist … anywhere. As of October, 2010, there are an estimated 123,126,928 domains registered across the top-level domains (TLDs): .COM, .NET, .ORG, .INFO, .BIZ, and .US.±  
Each domain consists of at least one web page. Some domains are humongous. Take Wikipedia, for example. It has a minimum of 1.74 Billion {that a B for Billion) words spread across 9.25 million articles that are translated into about 250 languages.  Every one of those pages has a unique Universal Resource Identifier (URL) or web address.
To differentiate one page from another, especially in domains as large as Wikipedia, Google, and Yahoo, the number of characters needed to differentiate the URLs can become quite long and extremely difficult to memorize or even write to paper (i.e. old tech). If you are a Twitter user, you know the prevalence and need to shorten long URLs.
To make it easier on web users, over offer URL shortening services to shorten a long URL into an address much shorter.  Google just released its own URL Shortener. This French site lists 155 websites that offer these services. If you don’t know French, I suggest you use your Google Tool Bar translator or another translator.  Each site uses a mathematical algorithm to reduce common number, letter, symbol patterns of the URL into a single character. Think of it as zipping or compressing the URL using shorthand.
For example, below are two URLs: #1 is a real site with 77 characters; #2 is the short version with only 23 characters. They both display the same website content.
  1. http://www.peoplewhositinthedisabilityseatswhenimstandingonmycrutches.com/
  2. http://bit.ly/9H8aG4

How long can a URL be? There is some debate about what is possible in the real world, but imagine a URL of 256 characters or more and you make one typo… Arrgh).  No matter, what is important to understand is the potential danger of opening shortened URLs.

The danger comes from not knowing or even being able to guess what the shortened URL will do for you or to you.
Given the choice between these two URLs which would you definitely try to avoid?
You can tell by the language of the second URL as to the possible intent of the site. You have no warning from the first.
I am not saying to never click on a shortened URL. Personally, I do so all the time and I use shortened URLs in my e-mails, website, and blog because they have some advantages. Should you trust shortened URLs sent to you by friends and business associates because you know them? That’s a judgment call for you. It all comes down to your risk tolerance, trust level and experience with malware protection.
One way you might protect yourself is to use an URL lengthener service. They reveal the original URL. Just as social media sites such as Hootsuite incorporate URL shorteners, eventually they will also hopefully offer convenient URL lengtheners. Until then, proceed with caution.
