Out of interest, what would you say are the kinds of bugs that using something like Haskell helps you avoid? I've had a look at Haskell before and while all the individual parts looked reasonable I struggled to understand both what an application would look like at a high level and what the inherent advantages are (not saying there aren't any - just that they didn't jump out to me).

In most languages I have learned I've generally reached a point fairly quickly (without hours) where I've thought "wow - this is cool!" and this is generally because of enabling me to do something more easily than in other languages - I've never got to that point with Haskell.

Note - this is just my own observation, not a criticism of Haskell or any of the resources I have used to try and learn it!
