Here are some suggestions I've seen on HN and elsewhere. Your mileage may vary. :-)

1) Work on something that interests both you and a cofounder. 2) Choose a potentially huge market. 3) Compete with big, dumb competitors in a market with no current winner. 4) Build something you would use yourself. 5) Build something for businesses, because there's less competition than there is for the trend-of-the-week in the Valley. And you can charge them money. 6) Choose an interesting hypothesis, and be prepared to pivot as you learn about the market.

Any other suggestions for choosing between startup ideas?
