This is also confusing to people. It means successful response, you can't for example respond with an error and claim the system is still available. I've seen some NoSQL databases claim they were still available because the user was getting an error message back.

Yes, I agree. It's not 'eventually consistent' but it's nearly available-in-CAP.

There are some elements on the CAP definition traps in the first post: http://thislongrun.blogspot.com/2015/03/comparing-eventually.... I also plan to do another post on this subject.
