nope,
try to understand the difference between split(regexp), map and map!
than decide for yourself
Look at this for example

"he, nice, guys".split(',').map!{|x| x.strip}
why would you use map! ?
try to put the above expression into a context
e.g.
x = ...

Hint: using map! on unreferenced objects is quite useless.

What about
x= "he, nice".split(",")
x.map!{|x|x.strip}

try
x.map!{|x|x.strip!}
would you like to use this?

If you want to walk do not learn to drive ;)

Cheers
