I (and many others) disagree with this completely . . .
In all the time I have been keeping SW I have never heard someone say that a skimmer is useless . . . thats just flat out crap. Unecessary . . . perhaps; useless . . . no way.
A skimmer serves many purposes in a SW tank and especially in a reef tank. It helps maintain the cleaner water conditions typically found on and around the natural fore-reef environments that most people try to simulate.
While some say that it removes trace elements, I do not feel that this is in any significant amount that can not be accounted for easily through regular water changes and additives.
For me, I run a skimmer 24/7 on my reef and always will.
Can you set up and maintain a great reef tank without a skimmer? Absolutely.
Are you going to cause any harm by running a skimmer? Most likely no.
