Looks like Amtrak: http://www.identityworks.com/reviews/2000/amtrak%20old.gif

Yeah, my wife's immediate reaction to that one was "so it will do as well as Amtrak?"

Strong agree. Sharp, professional.

But it has nothing to do with Haskell in particular... to most people, this just means greater than, lambda, equal to. This is doubly confusing, because >= usually means "greater than or equal to".

I agree that simplicity is very important, I like this one best: http://haskell.org/sitewiki/images/2/21/Haskell-apankrat.png

It's not '>=' it's '>>=' the Haskell monad binding operator.

(I also agree, that logo is pure awesomeness)

I know, but most people don't. Your logo can't be designed only for people who know the language.

Most people think >λ= means "greater than" "lambda" "equals", not a clever play on monad binding op and lambda...

Perhaps you are right that for most people the logo is meaningless. However, I find it looks like a fusion of >>= (Haskell's binding operator) and λ (the symbol of functional programming).

Great logo!

Personally, my first impression is that it looks like a subway system's logo: you have arrows on the left to designate travelling, rails on the right, and the various strokes remind me of the complexity of the interconnected lines of a subway system.

Just a thought.

Agreed. That one is solid.
