Im sure you meant that in a sarcastic way, but that might not be a bad idea. A lot of the dotcom bombs were not bad ideas in a universal sense. The technology, culture, adoption & know-how just wasn't there in 1999 and wasn't going to be there by 2000.
A lot of people are still ordering physical products online for the first time. A lot of offices paying for a webapp for the first time. In a lot of senses 2012 is what 1999 expected 2002 to be.
If you grab a list of 100 failed 1999 companies, you have 100 things that people thought were going to be big in 2002. Worth exploring if you're looking for ideas.
