Good article anyway! I think it's mostly fair. Although when people a secretive of their ideas, it's also that they don't want their incomplete or incubating idea out there amongst colleagues and friends. Inevitably someone asks, (and it might be your mum who asks) "so how's the internet-enabled frypan idea going?", and then you have to talk about it as if it's real to someone who probably can't help you with it anyway.
