...don't read the Billings Gazette.
About once every week I check out newspapers in other cities. Today I went to the Billings Gazette and clicked on a link. I got the first couple of sentences followed by a survey question I was required to answer in order to read the entire article.
Uber (a ride sharing app) in San Francisco. I clicked the "Show me another question" link and was asked how many times I used Lyft (another ride sharing app) in San Francisco. I clicked again and it went back to the Uber question.
Two points to consider here. First, I had no idea that everyone in Billings, Montana traveled to San Francisco. And second, we all know how reliable online surveys are.
