In Seamanish: The sound of the event-driven hordes stampeding to the  
cooling waters of semantic vocabularies has been not unlike that of a  
dripping faucet.

I wasn't suggesting that I liked "JohnsonPhotometry" or "rMagnitude" -  
they came from the IAU thesaurus.  This does show that too many  
possibilities will be a pain: do I use Rob's system+bandpass+magnitude  
instead of IAU's system+rmagnitude?   Frankly, I'd generally prefer  
Rob's choice of terms.

Another sign that VOEvent could do us all a service by forcing down-to- 
earth solutions to down-to-earth problems.
