Good point about the private posts later-on into July.
It's possible she's just run out of things to write about for the time being; the rants are pretty extensive. She was also really getting into the one story she was writing, about the Impulsive Lesbian Gypsy.
That said, if she wanted to take a break from the rants, or quit, I would think she would just post a comment saying so. Something like "Well, I'm done" or what not.
