The specifics of Open Tagging are crazy complex and we could spend an entire devblog talking about the system behind it.

We're also putting tons of polish and love into all four of our classes right now because we want to start diving deeper into them in a very public way in the near future. Wait, did I say four? It's six, I meant six.
That's about it from us; it's time we head back to our desks to keep working towards the next phase of beta. See you next week!
