A small berry makes everything you eat afterwards make sweeter, as the NY Times reports:
[A] small red berry called miracle fruit ... rewires the way the palate perceives sour flavors for an hour or so, rendering lemons as sweet as candy.
The cause of the reaction is a protein called miraculin, which binds with the taste buds and acts as a sweetness inducer when it comes in contact with acids...
...limes were candied, vinegar resembled apple juice, goat cheese tasted like cheesecake on the tongue and goat cheese on the throat. Bananas were just bananas.
The venture capital industry has its own version of these miracle fruits. In 2005, the miracle fruit was social networking. In 2006, user-generated content, and in 2007, web video, when mentioned in a business plan, made made it sweeter.
I am not sure what the miracle fruit in 2008 is. It seems to be a cautious year, so maybe it's positive cash flow.
