I liked the article but I feel the CAP theorem is again misquoted; it often leads to misunderstanding. From the article -
"but they would still confront the reality of the CAP theorem: your system can be consistent, available, or partition-tolerant, and you can only pick two"
The CAP theorem states that in the event of a network-partition you have to choose one of C or A. More intuitively, any delay between nodes can be modeled as a temporary network partition and in that event you have but two choices either wait to return the latest data at a peer node (C) or return the last available data at a peer node (A).

Edit: Switched C and A
