@JONNYSBRO, I was never a super fan of Lisa's. But then again, I'm not a super fan of any show hosts. They're sales people. Some do a far better job than others. I prefer to be given the nitty-gritty of the product being sold over how amazing it is and given the Fifth Avenue, Hampton's and Ladies who Lunch spiel. I fall into none of those categories.
I certainly do not know the reason Lisa left the Q. But I, like others, have my own speculation. I think the Q chose not to renew her contract. There are people who think they ARE the main event in businesses, but those same people forget that NO ONE is indispensable. Personally I think Lisa got way too big for her britches and thought whatever she demanded she'd get and the Q's management thought otherwise.
As far as Leslie and Judith - they've landed on their feet just fine without Ms. Robertson. Both sold their companies for hefty profits and neither have appeared on her Facebook begging for her help.
Lisa's offerings are overpriced, run of the mill, nothing special. The whole business of hers seems pretty sad to me.
