Taking a look at the Google+ API, I ran into the requirement to accept the Google+ Platform Terms of Service. Being a legal as well as computer nerd, I decided to actually read the damn thing. At first the terms looked reasonable, but it fell apart for me in sections 4 and 5.
TL;DR I'd have trouble taking a *paid* position that required me to agree to some of these terms, much less accepting them in order to pursue my hobby. I'm considering deleting my Google+ account now if this is Google's idea of "opening up" their system.
