  • Why you should build an application (even if it already exists) about 2 hours ago
    • Well done post. You could find a reason not to do anything. Google? Check out the search engines that already exist and own the space. Apple? No one wants a computer for personal use. Dropbox? File storage has been done and no margins. Twitter? 140 characters is worthless. Vizio? Enough TVs exist. YCombinator? WTF are you going to do with $15k.
      I could go on and on and on. Seriously, just fucking build it. If for some odd reason NOTHING at all exists like what you're doing, a competitor will come along that does. There is nothing and I mean nothing that a smart team of 20 somethings can't build nowadays. At worst, you'll have something that you, yourself love. That's the key to all of this: Build something YOU want, then adapt it so it works for a broader range of people if need be. If the tshirt for getting accepted to ycombinator is: build something people want and the tshirt for getting acquired is: i built something people want, the tshirt for getting asked to interview/demo should be: i built something I wanted.
  • Dropbox (YC S07) Raises $7.25M, Crosses 3M Users about 2 hours ago
    • Pretend I have a machine where you insert a quarter and, a year later, a dollar pops out. Do you a) insert the quarter you have in your pocket, wait a year, and then put all four quarters back in or b) go to the bank, borrow as much money as they'll give you, get it changed into quarters, and start stuffing the machine?

      A freemium startup which has a good idea of what customer lifetime value is and what customer acquisition costs are is, essentially, a quarter-into-dollar machine.

      This factor becomes particularly acute when the ultimate goal of the startup is to sell their quarter-into-dollar machine for some multiple of the number of dollars it has produced in the most recent year.

      [Edited in response to the above post going grey: Please do not downvote the post above me. He isn't being malicious. The big picture strategic view is non-obvious and many smart people need to have it explained a few times for it to sink in. If you wish to correct the misconception, either explain it or upvote an explanation.]

      [Edited to add: P.S. The expert on "(LTV > COCA) + source of capital => blow the doors off" is Dharmesh Shah. He has been banging the drum for a few years now. Example:

  • Seesmic Ventures Into Mobile With Powerful New Apps For Android And BlackBerry about 2 hours ago
    • This is a pivotal moment for Seesmic because the startup is now conquering all the mediums—web, desktop and mobile. I sat down with Seesmic’s co-founder, Loic Le Meur, to test out the apps.
    • While Twitter rolled out the geolocation API yesterday, Seesmic hasn’t integrated its API into the app. But the app still features a geolocation tool that lets you embed your location in a Tweet via the Android’s GPS, which will show your location on Google Maps.
