Until I read the post about how the name was selected from a list of computer-generated options, I (and apparently a few others here) thought it was a play off of, "ni' night." This made sense to me: you start Ninite to do unattended installs and then head off to bed.

Regardless, I think the name is actually pretty good. The issue for me is that the site has so little branding and personality to it that nothing reinforces the name. It's great that it gets you to the functionality right away, but I think you can preserve that quality and add some branding elements that reinforce the name.

Two ideas jump immediately to mind. The first is to play off, "ni' night," and use a darkened children's room, the night sky, or a children's bedtime book theme. You could add a dark background with a memorable graphical element such as a poster bed or the moon. The second is to conceive of "Ninite" as some sort of cool new chemical element -- a laboratory, the periodic table, or chemical structure diagrams could serve as themes.

Regardless, I'd move "Featured In" to be a horizontal set of badges below the screenshot and place a large logotype to the left of the screenshot with the tagline, "The Easiest, Fastest Way to Update and Install Software."
