Interesting, never heard of Dvorak before.
Skimming through the wiki entry, I can see why a switch could be beneficial for most of us. I don’t see anything speaking against it, though, I am satisfied with my 90something wpm. :p
The change would need to be radical and fast. I imagine having to learn both could be quite confusing and rather painful.
Playing the same map over and over tends to get boring over time, so the level editor is a great addition to keep the ‘pros’ happy. Though, not without a drawback. Due to the masses being beginners, ‘Luck Levels’ are voted up while harder one’s are getting deleted instantly. I certainly hope I’m wrong but soon we will be playing random jumping lvls only.
In my mind that’s a bigger issue than troll maps since I haven’t seen any for days.
