Google trends ranks the frequency of searches by region, language, city, etc. Searching on 'techno' or 'detroit techno' was disappointing, but looking at the searches for some prominent techno artists produced these factoids.
1. Jeff Mills as a search term has trended down slightly since 2004 2. Richie Hawtin has trended up since 2004 3. The city generating the most searches for Jeff Mills is Zagreb, Croatia 4. The city searching most for Richie is Medellin, Columbia. 5. The city searching most for Derrick May is Amsterdam, Netherlands.
From this I conclude that potheads like Derrick May, cokeheads like
Richie Hawtin, and people who like Jeff Mills are ... Croatian. I'm being humorous here, so please no email from offended Colombians or Dutch. I know that most Dutch people don't smoke pot, and most Colombian cocaine is consumed in the US. I will persist in stereotyping Croatians as dancing fools, though. http://www.google.com/trends?q=%22derrick+may%22&ctab=0&geo=all&date=all http://www.google.com/trends?q=jeff+mills&ctab=0&geo=all&date=all http://www.google.com/trends?q=richie+hawtin&ctab=0&geo=all&date=all
