It's interesting since, apart from all the talking about the social network in real life (didn't it use to be 'always' in real life before the internet?), we will probably see more and more of entrepreneurial attempts to include time in their explicit vision (there is plenty in the implicit vision).<p>Pg explains some of the underlying idea already in a few essays, like <a href="http://www.paulgraham.com/procrastination.html" rel="nofollow">http://www.paulgraham.com/procrastination.html</a> and <a href="http://www.paulgraham.com/selfindulgence.html" rel="nofollow">http://www.paulgraham.com/selfindulgence.html</a> , and we can see how this emerging concept of time well spent vs time wasted, and what their meaning really is, sooner or later will make its way into products.<p>In the future the way we spend our time will be so important since time will be so precious, that there is lots of space for innovation.<p>There is lots of ways to, for example, save time through software, kind of by definition. The app that saves me 10 minutes a day for catching the bus at the right time is valuable. The concept of bus itself is a way to save time. That's always been around.<p>But it's interesting to see ideas that relate more on the time that you are consuming somewhere, as opposed to what you are consuming.
