Uncanny. I can claim in true honesty that I had a remarkably similar vision for a comprehensive life 'experience quotient' app not even 2-3 weeks ago. The travel portion looked very similar: GPS enabled tracing of a global map space with percent coverage. But travel would be but one table in a comprehensive database of life experience: financial, relationships, science, arts, drugs, sex and everything else worth living for. An algorithm would tally a grand 'statistic'. It's the stuff of Borges' wildest fantasies, n'est-ce pas?
