More aggravating are the ones who think they're the next Steve Jobs and just need their Woz.
If you really, truly care about solving some problem, it should drive you crazy that there's something that you have no idea anything about. IMHO.
And my response, every time is : "Stop talking about it and do it - or don't."
I mean, if you're not prepared to knuckle down and do the work yourself - do you actually believe in what you're doing?
These words were said to a very drunk me in a bar in London some 12 years ago, while I was fucking about with my first botched trainer-wheels startup (social networking for the elite - got serious traction, but we lost interest), and was garrulously asking some poor fucker what he thought I should do about idea X. That was his off-the-cuff response, but I've lived by it since.
Most people I heard asking that question had no clue about technology, and more importantly, never showed interest in understanding the basics.
My feeling was that they thought of such partnership as a way to get someone work for free.
