@dwitchell yeah man. For now, @mentions are really our only means of carrying on a conversation. Which is cool, although it can be a bit awkward publicly - kind of like now . But, we've embraced it, particularly for the time being.
We're currently building out commenting and we hope to drop a simple version very soon. After that there's a few smaller, more interactive social features on the way to private messaging. All of these features have been designed, but we're learning as we go, iterating a bit and building things in a step-by-step manner.
The whole process is super fun, very excited, a touch never-wracking and really just kind of feel right.
