One goal we have for Dota 2 is to have as many people playing and enjoying the game as possible. To do so, we suspected we'd need to encourage behaviors that have positive effects on the game and community and discourage behaviors that have the opposite effect- like causing other players to play less or not at all or to discourage them from trying out the game in the first place. One of the things we also suspected was that we wouldn't be able to tackle that kind of problem without releasing the game - it's the sort of thing where you need a lot of data to know whether or not your changes are having any effect.

Now that Dota 2 has been out for a while, and gathering a nice mix of new and original Dota 1 players, we're able to gather data to find answers. One of the first things we dug into were the factors that contributed to a player quitting. While it might seem obvious that someone is more likely to quit if they have a negative experience in a game, we've learned in the past that we really need to test our assumptions to make sure we're not fixing the wrong thing. Interestingly, some of the factors we assumed would affect leaving didn't - for instance, the outcome of matches doesn't correlate at all to the likelihood of quitting. Losing a bunch of Dota 2 games doesn't seem to cause people to quit. But one thing that did stand out in the data was the amount of negative communication between players. Put simply, you are more likely to quit if there is abusive chat going on in your games.

So, further investment in discouraging negative communications seemed like it would be valuable. But where to draw the line? Should we allow all (potentially) abusive behavior in-game, or should we work to diminish it and push players more towards the positive and collaborative side of things? We don't want to restrict anyone's speech nor prevent anyone from speaking their mind, but for everyone who feels slighted by their inability to say exactly what they want to their teammates or opponents in-game, there is someone on the receiving end of that criticism who is having just as bad an experience (or worse).

After some discussion internally, we reached the decision that it seemed in the best interest of the Dota community to not push away players who actually enjoyed the game. As a consequence, this meant restricting the ability for some members of the community to say whatever they want. To put it another way, we only want people to quit playing if they actually just don't like the game. That thinking led us to the current communication ban system. Its goal is to reduce the toxicity that occurs verbally or via text chat, and as a result, to avoid causing players to quit the game solely due to negative communication experiences.

Now that it's been live for over a month, we're able to see some of the effects it's having, and the conversation the community is having around it, and we felt we should answer some of the questions we're seeing out there and pass on some of the data we have.

First, a couple of notes on the implementation:
<ul>
<li>Multiple people ganging up on you to report you in the same game has no effect on whether or not you are banned. We are looking at patterns of behavior over time only.</li>
<li>If you are currently communication banned, any communication reports you receive in that time period do not contribute towards, nor result in additional bans.</li>
</ul>The system is not yet ideal, but we felt it was better to gather data on this first step before trying to complicate it with extra nuance. We've changed the algorithm several times already, and we'll continue to update it in response to the community's feedback, and the data we're gathering.

The community has once again surprised and caught us off guard by reaching the second Stretch Goal in <a href="http://www.dota2.com/store/itemdetails/15162">The International Interactive Compendium</a> already, adding over $250,000USD to the International Prize Pool. Our original plan was for the International 2013 Courier to be able to ride a small set of mounts, and now the art team knows the community demands more. Here some concepts for some of the new mounts they now have on the to-do list:

Given how much faster the community is reaching the stretch goals we set up, we've decided to add some more, based on the many conversations we've seen the community having around the compendium. In particular, the big gap between the 2nd and 3rd is something we're addressing. More on that tomorrow.

Don't forget that the Western Qualifiers for the International 2013 started this morning over at <a href="http://qualifiers.thegdstudio.com/" title="TheGDStudio" target="_blank">TheGDStudio</a>. Good luck to all the teams involved!

Each year we spend some of the planning time for The International trying to figure out ways to improve the connection between fans and the players in the tournament. We know that the majority of our viewers will be watching the tournament unfold over the internet, so we'd like to make it easier for an online fan to dig deeper into the event, the teams, and the players. In addition to wanting more detail, we know fans also love to compete with each other at predicting tournament results. This year we're taking our first shot at addressing all of the these concepts, with an additional step that we hope will result in the tournament itself getting bigger and better as a direct result of fan enthusiasm.

Today we're announcing <i>The International</i> <a href="http://www.dota2.com/tournaments/international/compendium/">Interactive Compendium</a>, a virtual book that will keep you fully up to date with the state of <i>The International</i>, and allow you to play games with other fans for fun and bragging rights. In addition to making you eligible for special virtual item drops throughout the tournament, it'll also allow you to vote on tournament-related community polls, such as the selection of which player should receive awards based on their play in the tournament. After the tournament is over, you'll be able to browse your friends' Compendiums to see how successful they were in their predictions.

Finally, to directly tie fan interest in Compendiums to the players themselves, we're going to redirect 25% of the revenue directly into the prize pool. That means the total $1.6 million prize pool for The International is now just the starting point. The Compendium will be available in the <a href="http://www.dota2.com/store/">Dota Store</a> tomorrow morning at 10:00am PDT. For those of you planning to attend The International in person, your ticket purchase will include a Compendium.
