I posted a circuit awhile back and a number of people said it would never work.
Well actually, going back and looking at the thread, only a single person said it would never work. The rest were people asking questions about what you were trying to do and discussing possible issues with the circuit.

So my point here is don't believe the nay sayers. There seems to be a number of people that want to insult and degrade people.
My point here is, before you go off and get an attitude towards criticism, realize that a part of designing circuits is listening to what people say--especially their questions. Engineering minded people are very curious by nature and will sometimes point things out by asking questions. Sometimes it is because they are right and sometimes it is because they just want to learn too.
