I remember getting access to Google+ first in my group of friends. I was up late and got in at like 1am. Nobody else was there. It was an absolute ghost town. No content anywhere. I thought, "wow I should treasure this moment. Soon and for the rest of time G+ will be filled with content!"
Of course you can start like that. Look all they need to do is pay MySpace Tom to come out of retirement and be everyone's first friend on Instagram threads.
Some will say, "well, why not Zuck?" Well, androids still have that uncanny valley effect and they're not quite as relatable.
