Which makes me wonder, how does everyone deal with the prospect of competition from Google?
I had an awesome idea for a startup, worked on it for a few months during graduate school...and then Google announced they were getting into the space. I just about crapped myself.
I seriously wouldn't worry about it too much. They either do or they don't it's a bit like the weather, it will influence you but since you can't control it you might as well simply adapt to it.
If it wouldn't be for that then you could never do anything at all for fear of some 'force of nature' coming along and destroying it.
And who knows, maybe you'll be better at it than they ever will be simply because you are focusing on just one thing instead of on 50.
A valid point. Most Google products never reach critical mass. But for a device like the iphone you are already using google maps. If its integrated directly into that, the barrier to entry is nothing.
