Sure, but it's often a clearer way to explain why a statistic is misleading.

In this case, my anecdote shows an example of why the steam hardware survey is not, and was never intended to be, an accurate depiction of what distros people are using overall. Instead, it's a depiction of what distros people are using for Steam, which is the point of the statement above mine.

Using anecdote instead of statistical data is a bad idea. But so is ignoring anecdotes simply because they're anecdotes, as anecdotes are often one of the best ways to find limitations in statistical data.
