A few weeks back I proposed a reskin of conduit to make it easier to learn and use. The proposal overall got broad support, and therefore I went ahead with it. I then spent some time (quite a bit more than expected) updating the conduit tutorial to use this new reskin. If you're interested in conduit or streaming data in Haskell, please take a look at the new version.
Thanks to all who provided feedback. Also, if you want to provide some more feedback, there's one more Github issue open up: RFC: Stop using the type synonyms in library type signatures. Please feel free to share your opinions/add a reaction/start a flame war.
And yes, the flame war comment is a joke. Please don't take that one literally.
