I learned Haskell around 2010 starting with LYAH followed by Real World Haskell. I too wouldn't recommend LYAH for actually learning Haskell in $CURRENT_YEAR now that there are manifold and much better resources on the topic now, such as Haskell From First Principles. LYAH was quite hilarious and entertaining, but I think its time has passed. I don't use Haskell a whole lot these days, but to this day Haskell is still one of my Blub languages.
