A little multimedia poem using metaphors
How to train someone that I know to improve their media literacy:
First of all, my friends,
I must get to the root,
When the computer is turned on,
first comes the boot,
By turning on a machine
That is described as virtual intelligence
Next I get to do
something of which I’m fond
And that is to type my name
and perform my own log on
Communicate is the next item
Something to do before I get bitter
And that is to let my friends know
That I am on by twitter
Into a world I must go
Its really not actual
This other world is really
Called something that is virtual
Once inside this other world
there is something quite bizarre
I now must communicate with
my own expressive avatar
Now my friend the lesson nears
I hope it’s not a dud
I really wanted to make this
Quite as clear as mud

The business area I am commenting on is the religious business area. The use of emerging media on religious sites various. I visited several religious websites and was looking for their use of emerging media. There were some sites that used quite a bit of different media and there were sites that were lacking in much other than text based information.
The design decision of which emerging media to use, in my opinion resides in the business goal of the organization. For example if the organization of the site were one of offering information to those that do not understand or present information to some that are seeking, I believe that the emerging media use should be based on the education templates such as those offered or written about [1, 2].

Electric Car reality?
While reviewing Technology’s Promise [Halal, W. E. (Ed.). (2008). Technology's Promise:Expert Knowledge on the Transformation of Business and Society: Palgrave Macmillan.], I too find myself desiring to comment on the predictions of alternate fueled vehicles that Halal has commented on. First of all I would like to say that I desire to have the electric car, hover car, and teleportation technologies as soon as possible. However, regarding the automotive technology, there are still some hurdles that need to be overcome. One of the technology areas, and in my opinion, still the largest hurdle at this time, is the power density of the alternate fuel being considered.
A great article from Design News [Murray, C. J. (2008). Auto Industry Working Hard to Make an Electric Vehicle Battery. Design News.], discusses the power density of the existing battery technologies versus what is contained within gasoline.
(Image inserted from "http://www.designnews.com/article/print/10574-Auto_Industry_Working_Hard_to_Make_an_Electric_Vehicle_Battery.php")
In summary, gasoline contains approximately 80 times more energy per volume than lithium-ion electric vehicle battery, and 250 times more energy than the standard lead-acid battery in cars today. This means that in order to extract the performance that exists today with gasoline engines, there has to be an 80 times improvement in the technologies that are used to make automobiles. For example if we use Halal’s assertion that the current gasoline engine is only 14% efficient, to get an electric engine that was 100% efficient would improve efficiency approximately 7 times. We still need a 73 times improvement somewhere else within the automotive technology, such as weight savings, wind resistance, etc.
If you couple this with the acquisition costs of the fuel, (the cost of producing the gasoline vs. the cost of creating the battery), again the gasoline still has the advantage. There are still many hurdles that exist before all electric cars can compete as a total system cost with gasoline vehicles. I believe, and hope, that all electric cars become an economical reality, but I am left to believe that if they become mainstream in the near future with existing technologies, it will not be due to its economical/efficiency advantage, but will become viable due to people willing to pay the extra costs of the inefficiencies for other real or perceived payoffs.
