Stealth mode is when a company is operating in secret for some length of time before launching their product or service. In many industries, creating a new product or service takes significant time and effort. During this time, being in stealth mode may make a lot of sense. But creating a new web service is not rocket science and does not take a lot of time or money. My rule of thumb is that it should take no more than 3 months to go from conception to launch of a new web service. And that’s being generous. I’m speaking from experience here. I developed the first version of ONElist over a period of 3 months, and that was while working a full-time job. I developed the first version of Bloglines in 3 months. By myself. It can be done. And I suck at it! Just ask all the engineers who have had to deal with my code.
I agree with all his points. Read it all.
I started going down the stealth route, but quickly dumped the idea for much the same reasons he says. With Ruby on Rails it is even quicker to do stuff, so there is no excuse to not get your app out in front of people.
