She hasn't posted any in years. That will put many off, but I think it is actually a neat marketing plan. She seems to be laying really low and turning her back to promotion. The best things I can compare it to are both food related: the "secret menu" at In-n-Out Burger or a ultra high end fine dining establishment not offering a menu to see, only offering a chef's special. It creates a bit of a buzz because everything is second hand whispers (full disclosure I have seen her several years ago and it was amazing)
I don't know if this has been an intentional plan of hers or if it is even a sustainable plan of action in a crowded market of Sp's. Many ladies have "retired" and let it be known that they would continue to see previously known men (sometimes for years after retirement) But I have never really seen a lady return to working and presumably begin seeing new men while only offering a "secret menu" It has been interesting to watch and I fully intend to catch up with my long lost friend sometime soon...So I guess I may become part of the secret society...Very interesting... She may have felt quite at home in a "Don Draper Mad Men" world
