Braille?

I think the catch here is we need to separate the birth names from the pseudonyms.

Amazon.com's founder is Jeff Bezos, born Jeffrey Preston Jorgensen.

Best supporting actress in Moonstuck is Olympia Dukakis, who played Rose (presumably Rose Castorini).

The Far Side cartoonist is Gary Larson, not Gary Larsen.  He has no nickname, as far as I know.

New hint: (redundancy aside) All of the individuals clued here have all done the same thing. Once you know what that is, the flavortext will become much more clear.

Voice acting?

arks

I think I got it. All these people aren't normally voice actors, but they have guest starred in different cartoons. What we need to figure out is whether they played themselves or a character.
Alyson Hannigan was on King off the Hill as well as a few other cartoons, but she always played characters (thus her space would be a dot)
Lance Armstrong guest starred on Arthur as himself (thus his space would be blank)

This may be Simpson's specific, though there's nothingI see in puzzle that hints at that
