I came to non-monogamy in a similar way, and tend to view my relationships much like she does. I like the distinction she makes between a "partner" (someone with whom you make life decisions) and a "lover" (someone with whom you have sex). I also strongly relate to the notion that an "intimate" can be one, the other, both or neither.
I can't imagine handling as many simultaneous intimate relationships as the author does, but I am open to much of the range she describes. The notion of living alone with frequent visits from partner(s), lovers(s) or other intimates sounds pretty optimal to me right now.
