Viewing this as a branding exercise is missing the whole picture. UberPOOL and Lyft Line will revolutionize transportation by convincing drivers to pick up passengers during their commutes to and from work to pay their gas, maintenance, and then some. They'll convince riders to get in cars with strangers for prices that make owning more than one car in a household unreasonable, even in the suburbs.<p>Doing that requires far more people to get comfortable sharing small spaces with strangers. Profiles are a step in that direction.<p>EDIT: Either I missed it the first time, or they added a big chunk to the article about Line. Regardless, the branding angle is far secondary to Line.
