Haskell's advantages lie in being pure. It can't be 'friendlier,' because friendly languages let you hack things up (and are impure) as opposed to the planning required to lay down some Haskell.
Haskell certainly seems friendly enough to me. It catches most of my errors before I even run the program, it let me hack things relatively quickly with very little code. Yes, there is that "purity" discipline, but I mostly think like that anyway.
Now, it certainly won't be friendly to one who routinely writes code like that:
if (foo)
if (bar)
do_something;
if (foo) {} // OK, do nothing
else if (bar) {} // OK, do nothing
else { do_something; }
(For the few who don't see the code above as utterly ridiculous, here is the better version:)
if (foo && bar)
do_something;
if (!foo && !bar) { do_something; }It is often an egocentric excuse to not lean new tools... As if programming was about making he programmer comfortable, as opposed to producing the best result possible.
