in reply to Does an idea have value?

 One thing I've found in the past is that I've been sufficiently intruiged by a question to go off and research an answer myself.

 Typically I'll spend a while reading the perl documentation, playing with some test code - then discover just before posting an answer that somebody else answered it nicely.

 This is enough to make me not answer, mostly, but I don't regard it as a bad thing because it's forced me to learn something.
