Participating on forums is fine and all, but in reality actions are worth more than words.

I think Valve can easily check and count how many people turned their matchmaking history to public in game options.

So, basically, if you support what DotaBuff does and you want to see progress in personal player stats, turn your mm history public. Tell your friends, teammates, fellow dota2 traders, everyone you know who plays dota2.

The more people will use public mm history, the bigger message it would send to Valve.
