World66 was my first travel startup. The idea was to let people write a travel guide of the world, wiki-style. It actually predates the wikipedia, so we might have been on to something. The site got sold and then merged with wikitravel. Wikitravel is still around, but world66 is not.
(German philosopher) Georg Wilhelm Hegel, on his deathbed, complained, "Only one man ever understood me." He fell silent for a while and then added, "And he didn't understand me."
