    IMO regardless of the results (I can’t see them) this Survey has no credibility. The Web site and the survey service they use are just too difficult to deal with. Anyone running their Web browser responsibly with full control over scripting will likely take one look at the mine-field of a Web site hosting the survey, and simply leave. This situation is like conducting a written survey using dirty paper with a foul odor. Expect an unreliable sample set.

    There are layers and layers of Blogger scripting bloat to hack through and in the end, even after allowing the Sway CDN (I’m a U.S. Ham traveling abroad), I’m still getting errors from Sway. Even when I throw all caution to the wind and allow all the scripting bloat and numerous unwanted iFrames, in the end I still just get “Error” from Sway. I’m using the latest Firefox browser with full visibility and control over all scripting via the excellent uMatrix extension. I could use one of my VPN connections to emerge inside the U.S., that may get me past the Sway CDN and their Geo-Jailer, if that’s indeed what’s going wrong. But then I would need to wade through all the scripting and iFrame bloat layers again. Nah.
