It's worth bearing in mind that when writing something side effecting (reading and writing to a database for example) in Haskell, it will be done imperatively.

There's definitely a bias towards the familiar however, it took me a while to get my head around the "FP way" as it were. The frustrating thing is that like you say most people are just trained in procedural programming with often at most minimal contact with anything functional which causes a kind of pressure on the whole industry.
