Demographer/Marketer-Filter: I'm seeking an exhaustive list/explanation of all the acronyms and mnemonics like DINK, BOBO, buppie, yuppie, slackers, boomers, etc., especially if it includes information on marketing demographics that focuses on lifestyle and consumption habits by zipcode. Free online resources (including journal articles available through university libraries) are much preferred, as are complete typologies over ad hoc descriptions. [more inside]

In my effort to organize a Los Angeles MeFi Meetup, I'm confronted with the fact that this is such a spread-out metro area that finding a generally-convenient location requires some high-tech assistance. Does there exist a web service or other program to which you can enter a list of zip codes (like on the 'MeFi Users Near You' list) and find out what area is the most 'freeway close' to the largest number of people? Or do you have any other suggestions how to 'triangulate' a couple dozen people?
