Mux — Video for developers
Arnold Kim:
Apple has finally started allowing developers to issue free promotional copies of their iPhone applications. Once an application has been accepted to the App Store by Apple, developers can issue up to 50 promotional codes. The codes allow the recipient to download a full copy of the application for free.
Interesting analysis from Mobile Orchard, multiplying App Store popularity (in terms of downloads) by price, to get a rough measure of who’s actually making the most money.
Seth Godin:
The only reason to answer the phone when a customer calls is to make the customer happy.
If you’re not doing this or you are unable to do this, do not answer the phone. There is no middle ground on this discussion. There are no half measures. Saving 50 cents a call with a complicated phone tree is a false savings. Think of all the money you’ll save if you just stop answering altogether. Think of all the money you’ll make if you just make people happy.
Antonio Carusone:
The Grid System is an ever-growing resource where graphic designers can learn about grid systems, the golden ratio and baseline grids.
Lovely.
Very impressive spreadsheet “data cleanup” tool. Check out the demo to see just how cool it is. (Via Andy Baio.)
Google Calendar’s CalDAV support is out of beta. What would make this really great would be for the iPhone to support CalDAV directly.
Seemed like a potential rival to Twitter at first, but never took off.
