TF2 has a new (official) blog!
Here’s a bit of of Robin Walker’s first post:
Now that we’ve settled into regular releases of content, we’ve found ourselves wanting a better way to talk directly to the TF2 community about the state of the game and some of the reasoning behind the choices we’re making. Our hope is that this blog will accomplish that, and give everyone some better insight into our development process as well.
Thanks to Major Malfunction for pointing this out!
