While it may be hard for those soaked in the tech community to believe, I can assure you that normal people are nowhere near reaching an "app wall". In fact, most people have no use for any of the apps that get all the press in the tech world.

Ask an average person if they have ever heard of Instagram or Foursquare and the answer is no. And I know it might be hard for you to believe but no, they have never heard of Quora or any other sites that are the stuff of techie wet-dreams. Hell, ask the average person if they use Twitter or see any need to and the answer is, once again, a resounding no. I have asked plenty of average people what they thought about Twitter, and almost invariably they respond with "What's the point? It's Facebook if they only had status updates."

We spend our day in silicon towers, endlessly debating the intricacies of sites, apps, and tech issues that in the end have zero effect on ordinary people. Did any normal person care that the Iphone might lose service if you held it in an extremely awkward way? Nope. Does the average person realize that Apple doesn't support flash on mobile devices? Probably not.

Tech bubbles, like the one we are possibly in right now, are caused because the tech community insulates itself from real people and the real world. If the VCs and the developers would climb down from their silicon towers and interact with the majority of people (i.e., not readers of tech blogs) they would find that most of what they are developing is bound to fail because it has no bearing in a normal persons life.

Just my two cents.
