I've come back to this list several times since I first saw it last week. Doesn't it freak you guys out that you're mining for ideas within such a small pie-slice of the human experience? There are lots of things that can bring a startup down. In my experience most founders are so close and in love with their precious idea that they only pursue evidence and opinions that support their position. So even if there is an opportunity to ask "is there a critical flaw that realistically should keep me from even starting it" most geeks will find a way not to take it. That's why Steve Blank's "customer development" reads as radical to many geeks but it's beyond obvious to people who develop products in the real world. Fact is, most startup concepts are doomed before the first line of code is written; not because of poor execution, but because the ideas just aren't that great — and they only ask people who love them "too much" to be objective for their opinion. When I tell would-be clients that their idea is not going to be a home run, that they should stop while they're ahead and take the time and money the were about to throw away and take their family on a nice vacation... some get angry, others thank me, and one fella bought a third of my company. TL;DR version: if your idea is on this list, you're not trying hard enough. Nobody needs your Basecamp clone, but everyone sits on chairs. Design a better chair.
