I smiled a lot at this post by Paul Carter:
Criticisms, Congratulations, Intarweb keyboard warriors and badasses (NWFS)
The whole post is good, but scroll down to "Let's see you do it."
That post sums up my feelings about those words. Just because you can't do it, doesn't mean you can't judge it, rate it, understand it, or form an opinion about it. That doesn't mean everyone should always be free with their opinions, but it does mean the inability to match a lift, a performance, or a result shouldn't end any chance at commentary.
