It's not gone. It'll be back.
I've recently moved house, and obviously that consumes a lot of time both before, and after the move. In order to write a Haskell article, I need to develop supporting code. I don't have much coding time right now.
On the other hand, it's pretty easy to knock out an article based on the knowledge gained during my Master's, and through my industry experience, so I'm writing on those subjects for a while.
Haskell will be back!
