I posted a pic on this website where people can rate your fishtank (in my case, a reef tank).

As an experiment, I set my location to Canada for the first week and I averaged 6.2. Then, I changed my location to USA and now my total average is 7.27 meaning that after I changed my location, the new votes were around 8.2 making my overall average 7.27. So, by simply having a Canadian location, I was getting 20% lower marks. I realize that the sample size is too small to make any conclusions but it was just an experiment that I thought was interesting. Feel free to post your pics for fun.
