Why use Skeleton when you can use Columnal or Goldilocks? From a brief read Foundation explicitly supports nested grids, it's handling of centering columns seems preferable, more than one type of button class, slideshow integration, etc. I recommend reading through the docs (http://foundation.zurb.com/docs/index.php http://foundation.zurb.com/docs/index.php) and if you're familiar with Skeleton you'll notice what's different. I've used Skeleton in the past but for future projects I think I'd go with either Foundation, Columnal or Goldilocks.
