One of the explicit goals we established early in our writing process was that we wanted to make Jar Jar's character likeable. So many people have such a low regard for Jar Jar as a character that we really wanted to turn that on its head and make him an entertaining and fun character in the comic. It was an enormous challenge, and we feared it might be too much of a mountain to climb, but we tried it anyway. We humbly hope that we've succeeded on some level.
In the movie, the other characters actually like Jar Jar (or at least put up with him, in the case of Qui-Gon), while the audience dislikes him. Here we want the audience to like Jar Jar (and Sally). It's interesting that one way to achieve that is to have him (her) annoy the other characters.
