I've thought of doing the same, but in cases where the word had double letters it feels a bit wasteful. And I guess that logically the best word to start with is one that contains as many as possible of the most common letters.
Sure, it's just boring. I've been using mostly decent starting words focusing on getting a lot of that classic Wheel of Fortune RSTLNE in there... but logically you should start with the very best starting word. Which means using the same starting word every single day. Which would get really boring.
Plus, the ESL crowd is kind of killing it. As a native English speaker, I should at least try to handicap myself a little.
One annoying bit about this game is it runs off your local clock. I guess it's nice that you know the new puzzle is up at midnight, but on US Pacific time you just feel way behind players on the other side of the Atlantic.
