The Tumblr, called "Betty Knows Best," features quotations pulled from the movie, various public interviews and Halbreich's book, as well as one-liners jotted down each day by her assistant.
The Tumblr functions like a quote generator: For every click, you get a new picture of Halbreich and one of her sayings. Among the sayings currently on rotation: "What do I recommend you take on a trip to Paris? How about a good-looking man." And: "What would I be doing if I weren't doing this? Drinking." More will be added over time.
At 86, Halbreich may be Tumblr's oldest user -- as well as its wittiest. The Tumblr was developed to promote the documentary, which is now available on DVD and on Netflix.
