That is better. We might also change "a fixed amount of extra work gets added" to "a single unit of extra work gets added." Even that is probably more vague than just coming to an understanding of what logarithmic graphs look like as 'n' increases. Unfortunately, that's sort of difficult to post here. I do like trying to improve the description though. Wikipedia has a great writeup on Big-O notation. Why didn't we have that when I was in college? ;)
