Done. A few suggestions:
1. You might want to consider adding a "decline to answer" option or similar on political orientation, similarly to what you did on income. I'm unsure as to what the American perception of those are compared to in my country where we as a whole are more liberal and the issues associated with the different political orientations are sure to differ. Sure you can take a guess, but it won't necessarily be particularly accurate and I'm uncomfortable with giving an answer to a political question I'm not sure of.
2. 99% of countries in the world do not use the imperial system for weighing things. Sure, your reach is much larger in the US so you get many Americans taking the survey, but please type it out in kilograms as well so the people who don't use obsolete and generally shitty measurements don't have to convert.
3. Who decided Germany and Denmark belong together on the pipe origin question? A lot of countries got their own line but you (someone) put Denmark (which is an arguably very big nation when it comes to pipe making, no doubt deserving it's own line) and Germany (which isn't to the same extent but still has some big names) on the same line? I fail to see the logic behind it.
4. Briar, meerschaum or... other? I see absolutely no reason not to put clay, cob and maybe even calabash on there. Oversimplification where it makes no sense while most other questions have good, exhaustive answers to select from.
