I think this kind of thing will occur only naturally if people get genuinely interested in Steemit as a platform and so far I'm definitely seeing the activity go up with all the censorship and so on going on in other social networks.

If someone is interesting enough, people can just register and they'll upvote them and so on, just like with all the other places. That will not only be good for the person in question but also for Steemit generally.
