The February 28, 2011 review discussed Show of Hands, linked to showofhands.mobi and App Store ID 336442597. It described answering questions and then exploring results, including views grouped by participant characteristics.
Those are features of the reviewed version. Current availability, participation rules and privacy behavior have not been verified from the historical page.
Read the question before the chart
A poll result is a response to particular wording and answer choices. Before comparing percentages, look at what people were actually asked and which responses were available.
Two questions about the same general topic can produce different kinds of answers. Keeping the wording with the result prevents a chart from being interpreted more broadly than the question supports.
Participants are not automatically a population
A voluntary app poll reflects the people who took part in it. A national-looking chart does not by itself show that respondents represent everyone in a country or any particular demographic group.
The original review emphasized the appeal of comparing opinions. That can be an interesting starting point for discussion while remaining different from a carefully designed survey.
Preserve the purpose without overstating it
Show of Hands brought asking, responding and browsing results into one mobile experience. This restored article records that workflow and the specific historical app, without turning its old sample of participants into evidence about what people think today.
