When will someone make a service that will truly revolutionize the way we use bitcoin? An app/webservice that would oversimplify the use of bitcoin, making it accessible to the common folk who don't want to spend time getting to know bitcoin. Also something that would mitigate the exchange risk/confirmations duration problem.
It's pretty depressing how slow innovation has been in this regard. 5 years later and user friendliness is still a lonnnnnng way off. No one has built even, say, an iphone app that lets you send bitcoin to friends with the "scary stuff" running in the background (interfacing w/ public keys, etc.). Normal people don't give a shit about interfacing with public/private keys. They want to click on a picture of their friend and send them bitcoins. This blows people minds in computer science that everyone isn't "technical minded".
In fact, the closest thing so far to being user friendly and "non scary" is probably Coinbase. Anything else I'd be afraid of recommending to a non-nerd. Seriously... would you send your grandma to blockchain.info?? lol
