Great article, well above the standards of Techcrunch lately. I agree with the seven deadly sins being the best advice on there. VC's want to know why people wont stop using your idea not why they will want too.
"6. What are the accelerating effects?" Roughly equivalent to "What makes you idea viral?" ?
Wow, seven deadly sins is one of the best pieces of advice I've read.
75 points without a single comment? WTF
"7. What’s your secret sauce? ... We hope to come up with Something Big in 2010."
Hmm. I harbor hope that he's kidding. I'm more and more a believer that the only secret sauce that matters is relentless execution and incremental improvement over many years. Sure, some companies will happen upon the magical product-technology-market puzzle piece that ends up being worth a billion dollars, but that's playing the lottery, not running a business.
