You can use ordinary highways or federal highways at first (so, being a hobbyist)
I would say, even more so than being just a hobbyist, what PeakD is trying to accomplish in terms of easy onboarding, fits very well into the ordinary highway analogy. They can onboard via an email, FB, twitter, etc. and just use the main features. Then, once comfortable, hop on the autobahn and use their keys to access more in depth features.
Great add on to my original analogy. Maybe @peakd could use it to summarize the difference between using private keys (autobahn) and easy onboarding/being a "hobbyist", (ordinary highway).
Thanks for your insight :)
