What sets Yahoo!'s offering apart (at least in theory--it isn't all delivered yet) is the focus on turning all of Yahoo's properties, services and content into:
- An open API based mash-up ready smorgasbord of development opportunity, complete with development environment and optional hosting in their infrastructure.
- A completely interconnected social network that differentiates itself by being a feature, not a destination. This, for me, is a wise move on Yahoo's part, as no one else is willing to say their network is simply a part of the overall user experience of a destination, rather than being a destination that users must conciously choose to navigate to to use its advantages.
I think Yahoo! is looking at an interesting play, though you have to wonder how they will steal developer mind-share from Microsoft and Google--that is, unless they become either Microsoft or Google...
