>The best part was that there was zero quality control, because anyone could edit anyone's map, so you constantly encountered variations and remixes of popular maps. Apart from a handful of very popular main maps, you often had no idea what you were going to get.

Absolutely the best part. It was so easy to modify maps and just try stuff. You could play a brand new game every night. So much creative flourishing, constantly inventing multiple genres. You might even give it credit for AutoChess since the Dota mod was inspired by a similar Pokemon WC3 map.

It looks like the most comprehensive map archive site went down and never came back up -- all those maps will be lost in time.
