If you'll notice, the guy with the Phonebloks idea wasn't technically savvy. His site crashed. He asked for help via Twitter - and got it.
I think this is a great idea. I was talking about entrepreneurship with some students 8th period yesterday - coincidentally about cellphones. This guy had a good idea and because there is a www he was able to get his message out there. 15 years ago this would have been impossible. There are many permutations to ideas, social media, information movement and speed, knowledge of the web. This is counter to the idea that 'the good ideas are all taken, or 'I don't have any tech skills so I am doomed'.
No you're not. Here is the update. What's your idea or product or service you'd like to sell? Perhaps you can get involved with these people via social media and learn from them?
