Facebook is worth 212 billion dollars by having a strong hold on your actions, interests, and preferences from 5pm to 9am and some fraction of your work day. If only it could get a legitimate way to suss out your interests from 9am to 5, that’s presumably twice the data it can mine to improve its targeting on you and me. Presumably, twice the Total Addressable Market. It’s just too lucrative to not fully know what you and I do for all those 8 hours. Investors should love this.
