Much of the API info is outdated now that the old API is obsolete and has been replaced by ESI. SSO is now used exclusively for authenticating your character.
The older info has been struck out for now, so it can serve as a bridge to the current way of doing things. Eventually, we'll remove all mention of the old API stuff, as it will no longer be meaningful to anyone.
For me it's WHs for ESRC, connection to Signal Cartel folks, and exciting/dangerous hacking. Null is for ISK, connection to other players, and relaxing hacking. I find in Null I have to watch Local always, so I'm not in alliance chat as much – but locals often wave and I enjoy meeting them.
I'm skilling toward running sites, it'll be interesting to learn if the trade-offs are the same for that.
