I'm trying to figure out the geography of hook-ups. I want to map m4m, w4m, and mw4mw as a percentage of all casual encounters post. This is the number of casual encounters posts over the number of apartment posts. I know that's problematic, because some places will have more apartments for rent per capita than others, but it's better than anything else I could think of (jobs, cars, etc). When I do the other maps and use all /cas posts as a baseline, I think the maps will be better.
Also, shoulders of giants stuff: I couldn't have done this without the craigslist shape files, GIMP, bash, awk, grep, and a certain degree of masochistic determination.
