The Sword has conducted a quasi-scientific study of Craigslist ads to determine the perecentage of "top/bottom" (problematic language -- see comments later) advertisements in various cities' M4M sections. Obviously of interest is the variation from city to city, with Houston home to the highest perecentage of ads from guys looking to get fucked; and NYC home to the highest % of guys looking to fuck.

Now, this study is all sorts of FAIL. For one, the methodology is wholly unclear. Were they picking ads from guys who identified as bottoms? Or ads from guys who were just looking to get fucked? Or did that all get lumped into the same category? Obviously, versatile ads and ads not seeking anal sex are totally thrown out of the picture. But most importantly for me is that Craigslist advertisements are not the same as, say, Manhunt profiles. Sampling Craigslist ads tells you something about the sexual culture of those cities, but its problematic for a number of reasons: 1) Repeated posters (and you know if you use Craigslist that there are a few dozen people in each city who post multiple times a day, seven days a week); 2) The relationship between people who post and people who do NOT post is wholly unclear. For every ad you seen on Craigslist, there are at least a dozen people looking (and maaaaybe replying) but never posting themselves. So the lurkers will never get sampled in this kind of analysis.

Let's compare this data to the data I collected last year from Adam4Adam and Manhunt in San Francisco and New York City. In a sample of ALL Manhunt and Adam4Adam profiles in both cities, I found that NYC had slightly more tops than bottoms (on both sites, about 35% tops and 28% bottoms) while San Francisco's numbers were comparable but skewed a bit more towards bottoms (33% tops and 28% bottoms -- with many more vers guys). Compare here the charts for just Manhunt for both cities:

Sure, my data from MH and A4A has its own set of problems (see original posts linked above for more on that), but I think it's MUCH less susceptible to the kinds of gross errors / data biases that come with sampling Craigslist. In short, don't get your puds in a wad over this info. Take with a big, fat grain of salt!
