The grid's a tiny place.

One of the stranger things about the grid is how socially accessible everyone is. In the real world, I can mail or email strangers and be confident that they'll never see my words - an assistant or the trash bin might. On the grid, I can drop a notecard and be relatively sure they'll notice it. With the current ToS, there's no guarantee they'll be the one to see it, but most non-corporate avatars are run by one person. Have questions about someone's projects or products? Just ask. Heck, the grid's small enough that most people read their own email. More often than not, they answer it.

There's a lot more possibilities when the noise-to-signal ratio is low.
