One of the purposes of the test was to see if they could improve voter turnout, and it didn't. A few countries like online voting, such as Estonia, but there's lots of paranoia about confidence in the integrity of the process. Understandable when you see how many commerce systems are compromised on a regular basis.
Myself, I would be ecstatic if the USA would adopt Australia's law of compulsory voting under pain of fines. If you don't vote, regardless of for whom you vote, you're giving in to the status quo.
