GFP? Really?  

The Prize for PCR, back in the 1990s, helped establish that the Prize can go to technical advances, as well as those that have deeper theoretical implications.  I didn’t have any problem with PCR, seeing as how the technique has enabled a vast range of advances in biology:  It’s safe to say that without PCR, biology in general would look completely different today.  

But GFP? Maybe I’m missing something, but for all the widespread use and utility of GFP and its friends and derivatives, is it really such a fundamental advance that it deserves the Nobel?  And in particular, for Chemistry?  Are there new theories or concepts in chemistry that wouldn’t have arisen without GFP?
