An idea that's easy to steal probably means that you either won't get a patent if you try (and you're wasting your time and money), or that if you do get the patent it might not even be enforceable down the road (and you'll have wasted even more time and money). There are a lot of clever hacks our there. Just because you don't see an implementation of it doesn't mean nobody has played around with the idea already. Aside from that, if you do get a patent and Google infringes on it, what are you going to do? If the answer is "nothing because I don't have (at least) six figures sitting around to take them to court", then don't get a patent regardless of whatever other reasons you might have for getting one. It's unfortunate, but patents are almost only useful for companies that have the financial resources to defend them.
