Kahuti has filled the void left by the demise of Streetlife. It is also without the safety and security issues which Nextdoor places all of its members in by default.
Kahuti are actually a hard working group for people attempting to make a (so far) brilliant website even better. They listen, they respond and where possible implement changes proposed by the members. The area you set for yourself determines what you see and who you communicate with. I was sad when Streetlife closed, I'm now happy they closed, Kahuti is far superior.
