Anyone know if there's any kind of common repository for Go projects? I like what I've read and am ready to drink the kool-aid but it needs something like CPAN or the public maven repos (preferably more like the maven ones).

Until then, it's awfully hard to get behind - if the development is going to follow Google's Java open source process (release a shiny gem every 4 months, zero community involvement), it's hard to justify making any investment in it. Guava's just a toolkit and is useful by itself, Go needs an ecosystem.
