*How Icefrog make this AWESOME map ??
I actually thought this was a joke the first time someone asked me, but I've been asked many times since, so I guess not. I'm just a person, 25 years old. While I am the only person that edits the map, I don't really consider it a one-man job. I have many beta testers that help out with testing and feedback. I'll save the story about how I picked the name IceFrog for another day though.
* How popular is DotA and why?
It is very hard to give an exact answer to that because there are so many different communities around the world with their own private servers, download sites and gaming centers. Some players do not download from getdota.com because they are either in a LAN or they have their own community sites local to their country for faster access, so a pure download count doesn't really cover it. A rough estimation from recent download counts would put it in the 5-8 million range. The game has been growing stronger each month, especially in Asia and South America as of late.
For the why, I think it is due to word of mouth. When someone genuinely enjoys a game and feels that it has a lot of depth and things to learn, they tend to tell their friends about it to join in with them without any marketing needed. It is because of this that the game is able to reach such a wide audience.
