The best idea was a company called White Label Dating. This is a real "wow I wish I had come up with that" kind of idea. White label dating allows local partners to use their framework to create their own online dating sites.

Dating sites will likely expand in to different life styles, locations, and interests (both sexual and not). This is probably the most clever Cloud solution we have seen and one that will be interesting to watch develop.
