An interview on GameSpy chats with Valve's Erik Johnson about DOTA 2, Valve's upcoming Defense of the Ancients sequel. Perhaps most interesting is Erik's take on community building in response to a question that suggested the original DOTA community is "toxic." Here's his reply:

We don't think the DOTA community is a toxic one at all. A huge number of users spend a huge amount of their time just writing guides to teach new (and experienced) players strategies for heroes, items, and high-level strategy for the game. In any community of this size, you're going to run into some people that rub you the wrong way... but I think that is true for, well, your average grocery store.

We also want to build more tools for the community to interact with each other, like allowing an experienced player to coach someone who is new to the game. Most new players come into DOTA via their friends, so we think this makes a lot of sense.
