Thanks :). That's an interesting thought, but right now we're focused on the value we can to these existing services. We have intentionally launched with a core set of features that we believe is the foundation for other things that become useful in this context, like search across integrations and versioning.

I totally agree that the game changes when you're trying to sell large enterprises on adopting something company-wide, but there is a precedent in products like Yammer that start by gaining adoption with small teams and organically grow out. That's the type of model we're interested in exploring.
