Why do people outside of corporations overwhelmingly use webmail instead of email clients? Long before rich email clients like gmail were available, people have flocked to the internet email client - messaging has been the killer feature of the web for a long time now.
But why?
The answer is simple: Overwhelmingly, users do not want to install programs, and users do not want their data stored on their computer. In that order of importance.
Let's examine the process of getting a popular, free, email client like Thunderbird installed. To do so, imagine that we're instructing our kindly aunt Tilly how to install it.
Now Tilly is no old fogie, she's been using Microsoft Word at work for over a decade now, and she knows her way around msn.com. However, she just decided to strike out looking for a new job, and wants to finally use that personal email address that came with her cable internet. She's got us trapped on the phone, and "we know computers", so here's roughly what we'll tell her to do:
And, ohmigod, we're not even close to done. She's still got to run the installer (3-4 clicks minimum), which involves selecting an installation directory (a what?), then open the program, open the tools -> accounts menu option, find the documentation for her service provider's email tools, copy them into the "add new account" wizard (another 3-4 clicks) where appropriate, remember her user name and password, and then download all the email she's had sitting there since she hasn't checked it ever.
Now, finally, she's ready to use her email client. It's just that easy!
Let's compare the process for getting her up and running with gmail:
Now, Tilly may not be the most technological mind around, but she's also no dummy. I know which one I'd rather direct her to do.
Desktop application install is a problem.
That's it.
Let me repeat it for clarity: The web, in your browser, is only really good at sending discrete data, displaying discrete documents and navigating in between them.
Phew.
The whole paradigm is absolutely superb at getting this job done. The system of hyperlinks, URIs, DNS, and HTTP over TCP/IP is the greatest achievement that computer programmers have achieved, a massive global effort that has managed to stay amazingly open and coherent. It "Just Works" enough to change the way information is distributed, businesses are run and even how society is structured.
Anything amenable to being represented as discrete visual documents has taken to the internet like a duck to water. Chief among them is email; check out the top 100 global Alexa websites and see how many "social networks" in how many languages are in the top 100. Sites displaying news (documents), photographs (documents), videos (strictly as documents), and information about software (documents) make up most of the rest.
What's left among those 100 is the elephant in the room; the Killer Internet Application: search. Even Microsoft's lame search engine finds its way into the top 100 because people will do whatever they need to in order to search the web; it's the only way to get an effective handle on the information in the Great Hyperlinked Mass. I believe it's the exception to my "web is only good at documents" theory that proves the rule.
Nowadays, Firefox is pushing <canvas>, Microsoft has released Silverlight, Macromedia has become Adobe, and Flash is the only one of the first generation technologies still breathing oxygen as a development platform.
Furthermore, with the invention of Google Gears, Joyent Slingshot, the aforementioned Silverlight, or Adobe Air, you might soon be able to (gasp) save files to the host computer! That's right, in 10 years we've almost gotten to the point where a program running in a browser can save a file on your hard drive and read it when you're offline.
The problem is that, fundamentally, a browser is still only good at one thing: documents. Its whole paradigm is set up that way. What does the "back button" mean when you're playing a game of asteroids? What does "home" mean while you're editing a photo? Does an address bar on an mp3 player need to be so in your face?
In the next article, we'll talk about how software installation came to suck so badly, with an eye towards how to go about bringing it up to the web era.
