I like this thinking as well. I kind of wish Haskell didn't overload operators to begin with but oh well :-) Just because the compiler can figure out what I mean because it has a great type system, I might not be able to figure out what I mean a year from now if I see ++ everywhere. In some sense, I prefer misleading function names to overly overloaded operators.
Yep, had the same experience. On the one hand, using monoids lets you delay some design decisions for later and lets you reuse more library code. On the other hand, it sometimes makes it really hard to see what the code is actually doing--especially if you use more than one monoid. For this reason on of the first advanced features I implemented in the (yet unreleased) scion IDE library allows you to look up the instantiated type of an identifier. Unfortunately, jumping to the definition (or documentation) of the monoid instance is a bit more difficult. Haddock should allow documentation on instance declarations...
