I like the idea, but is anyone else worried about the user interface? I don't like the thought of any site I happen to drive by registering their ability to handle intents. When it does become time for me to edit a photo, I don't want 50 choices popping up, nearly none of which I remember. And, it seems rife with phishing opportunities.<p>I'm not sure what the answer is here. I also don't want to be asked every time a site wants to register an intent. If you just make it opt-in, it seems like most users will simply miss the opportunity to do so.
