FLASH disk as swap

This doesn't correlate with my experience...
But then again, my experience can be wrong.    :) 

What I (believe to) have seen however, is that Linux wants swap no matter

I also tend to abuse the memory though. 

Is there an "official" answer for the question "Does a Linux computer need 
swap?"
ET 

PS: Yo initialize a swap partition with mkswap.
