I'm starting a new project and I've been thinking about Foundation for a while, I'm going to take your recommendation and go with it. Any major differences between Foundation and Bootstrap that might catch someone coming from Bootstrap out, or is it plain sailing?

The only downside is the javascript libraries are a bit underdeveloped and lack the large OSS-community scrutiny that Twitters benefits from.

But the basic stuff is pretty similar, so it's easy to switch.

I actually started a project with Zurb, and switched to Bootstrap, because it offers a bit more, and looked a bit better out of the box. I think Bootstrap has more momentum, which can be important for these kinds of things.

One of the guys who built Bootstrap actually built Foundation previously when he was at Zurb. Blanking on his name right now.
