Playdota.com

This is the main Dota website since Dota-Allstars.com remained into the possession of someone else than the Dota founder, Icefrog.

Having cool graphics, the website playdota.com contains good guides, informations about the heroes/items from the game, tools, forums, etc.

Others interesting websites regarding dota during the time was dotaportal.com, dotawarcraft.info, and many more.

What playdota.com is missing is a pro design.
