the real (short) meaning of mobile's rise.

Most web applications are about fitting themselves into people's computer using routine.  Whether this is embodied by RSS feeds fitting blog reading around the workflow of other tasks, or about fitting social interaction into computer time at work and home through instant messaging or social networks, tying an application to a computer meant tying an action to a location or mindset.  I didn't think of it this way at the time, but IM probably helped me get more homework done in high school, because it added an incentive to sit in front of the computer and enough distraction that actually doing the work didn't seem arduous.

Mobile applications remove the location bias from these activities.  So, Facebook and IM and GReader, etc etc etc are now fitting into my actual living routine, and the adjustment is notable.  Email is not something I check when I get to work, when I get home, etc.  Email is a way of reaching me at any time, suitable not to a location or time, but to a type of message.  Same thing with Facebook and IM.

This isn't a huge difference to the people who are spending 8 hours a day in front of a monitor anyways, but I start to feel it when I spend more time out in the city, or on location for work.  The change is notable enough that even my laptop is starting to feel cumbersome, which I would have found absurd a year ago.  My social and work information flow / social actions are becoming tied only to the flow of information, and the way I choose to connect to people.

What does this mean?  It means that it's no longer enough to make something seamless in integration with the way people work, or the way people use a machine.  It's becoming necessary to make something that seamlessly integrates with the way people want to connect.  Tying your service to a work-station, or a single machine, isn't a good idea.

If I'm going to be mobile in terms of space, you need to be mobile in terms of platform.
