It is very interesting to see the number of families that are posting on Steemit now. I have seen several users create accounts for their kids and while not all of them post that much, the possibility is there. I think in the end it will be difficult to toe the line between family friendly and censorship free. I guess the good thing is while the Steem Blockchain can remain free of censorship, the individual front ends can do their own filtering if they so choose. We need to be okay with that though and not go into an uproar over censorship. If you don't like how the front end you are using handles content, pick a different one!
