• Twitter Sees Its 20 Billionth Tweet writes  Marshall Kirkpatrick of ReadWriteWeb.
  • Startups die for not having customers, so STOP thinking about how to scale. Alessandro Orsi says focusing on the architecture and scaling possibilities of your app for millions of users is just plain dumb...concentrate on marketing...concentrate on user experience. Alessandro is perfectly correct, but this isn't the year the 2000 when the default architecture that is easy is also not scalable and when sites were built from scratch one painful user at a time.  Today neither is tue. In the era of social networks, where Facebook has 500 million users, successful applications can and often do spike to millions of users seemingly overnight. And you have to have some architecture. With today's tool-chains you don't have to choose easy and non-scalable. There are other options. Of course, it's all pointless without customers and that is what you need to worry about, but it's a false choice in this era to think that's all you have to worry about.
