On the excellent guide to Social Media careers by
@Carl, I've read that maxing the Internet Celeb career gives a new computer interaction "Represent Anyone...," which allows a sim to give another sim a career performance boost.
I've had a sim consecutively use the Represent option on his two sons, one of whom maxed his career (the other's at Level 9 currently).
I followed the usual strategies to boost the sons' job performance bars (Negotiate Bonus and pre-work mood boosts).
Nevertheless, they didn't progress through their career levels any faster than usual (though they did the Public Relations & Charity Organizer careers, so I'm not exactly sure what "usual" means for these two new careers).
QUESTIONS:
(1) How does "Represent Anyone..." actually work?
(2) Do we get any signs that it's working?
(3) Is it worthwhile keeping an obscenely wealthy sim in this career, just for the Represent bonus?
Unrelated comment about gaining followers for Internet Celeb:
Although the guide says to that the Livestream Let's Play action needs to be done until completion, it can be cancelled after a few seconds for the same amount of followers.
