Twitter just announced they are suspending non business travel and events, including South by Southwest.

The effect of the virus will probably have more corporate decisions to limit travel. I originally posted this thread in the majors forum because I think it'll affect hiring.
UA initially stopped hiring, then made the decision to cancel the 3/3 class. My guess is they are anticipating more of a drop off as people cancel or postpone their trips from fear of the unknown.
