How would that be useful? If you want a domain and it's available, you can just register it. If it's not available, then listing it here won't change its availability and -- worst case -- will make it more expensive.

A list of available and suitable domain names seems like a bad idea... We already have squatters snapping up expired names. Publishing a list of useful and desirable names practically guarantees that someone will register the whole list just to squat on them.
