Why do I need to register to try it out? I'd be happy to spend a few minutes of my time trying something new, but having to fill in all this information is too much friction. I won't bother. A button that allows me to create an anonymous test account with one click would be nice. If I like the service, I would like to turn my test account into a proper account, keeping my data. If I don't like it, and abandon my test account, you can delete it automagically after a month. Please do keep me logged in the whole month, though - I might change my mind and come back again.
