What's a good free hosted wiki with source code highlighting?

Question

I'm currently using Google Sites to publicly document my dev workflows and commands. However, Google Sites does not have a source code syntax highlighting system in place. Is there a free alternative to Google Sites with syntax highlighting? The solution I'm looking for need to meet the following requirements:

1. Free hosted service
2. At least 100 MB of space for free users like Google Sites
3. Has a nice editor with the whole web 2.0 feel and look
