I don't know if a personal echo chamber is such a bad thing in a pseudo-anonymous internet community. Look at what happened to 4chan and voat, where a bunch a racists decided to take over those sites and it was relatively easy for them to do so. They destroyed whatever community was there before their takeover and now both of those sites are known as racist sites. Compare that to hubski, which has a built-in echo chamber mechanism (I think you when block someone, they can't respond to you), and it's much harder for the site to be taken over by an outside group. The community just blocks the outside group and the outside group just ends up talking to each other in their echo chamber.
