Would you fund this startup?

Quora recently posed the question "What are some of the most ridiculous startup ideas that eventually became successful?" There list of crazy startup ideas that have actually become huge successes amused me; for example here are their first two:

• Facebook - the world needs yet another Myspace or Friendster except several years late. We'll only open it up to a few thousand overworked, anti-social, Ivy Leaguers. Everyone else will then join since Harvard students are so cool.
• Dropbox - we are going to build a file sharing and syncing solution when the market has a dozen of them that no one uses, supported by big companies like Microsoft. It will only do one thing well, and you'll have to move all of your content to use it.
