Be Agile in your Company Vision from http://www.sitepoint.com/article/application-fluff-hot-air/

In fact, there's no need to even have a vision. If you've executed your promotion strategy correctly, people won't care what your application does -- they'll be so dazzled by the flashy site and use of cutting-edge technologies that they'll forget that they've never actually used the thing.

Not having a vision makes you more adaptable. If you want to take your application in a different direction, you'll find it much easier to do so if you haven't committed yourself to any particular path.
