Roundup: Filmloop revisited, Quattrone back, Greystripe's ads, Healthline and more

Healthline's new Symptom Search—Healthline, the health search engine, released a feature Tuesday called Symptom Search. Type in "knee pain," for example, and it will give you 22 different possibilities of what is causing that pain. Sometimes you might have multiple symptoms, say knee pain and fever, in which case you can put both those terms in, and you get back a more refined list of causes.
