Whether it's for business, family, or girlfriend reasons, you'll inevitably be forced to travel to exciting destinations with undesirable companions. Ditch your decaying coworkers/potential life-partner and meet up with a friendlier face with Where Are You Now.
An appealingly well-constructed, globe-hopping social networking site with over 8 million members, WAYN is just now picking up in the US after establishing itself in Europe (hoping to succeed where fanny packs failed). Just create a profile and input the when/where of your upcoming trips, and WAYN'll spit out a list of people who'll be there at the same time -- either fellow travelers or gringo-/gaijin-friendly locals who'll be happy to show you the dirtiest corners of their fair cities. Sort results by age, nationality, and sex, then cruise the profiles for the kind of reasonably normal people you could kill time with, whether it's wing-and-pitchering a midnight Bears satellite feed in Mumbai or exploring the various pleasures of Amsterdam without having to tell your boss, "Leggo my spacecake, sir".
WAYN also lets members share travel slideshows and diaries, and hosts forums on thousands of locales -- even if you don't feel like grabbing bratwurst with "LarsMetal666", you can still follow his directions to Frankfurt's most reliable Yugo rental, then flee your company off-site at a robust 23mph.
