Wow, I never knew about the Eternal September phenomenon but now I understand why online communities take a turn for the worst after becoming popular.

The same thing happened to YouTube after 2009. And as for hubski, only time will tell, however I'm not so sure any kind of moderation could solve the problem, only delay it.

Let's say hubsky gets flooded with people posting shit content and comments. The people you follow will have a harder time finding good discussions, thus you'll have a tougher time. This creates a pressure to conform to the tone of the newcomers and before we know it, we're back to where reddit is now.

At least that's my hypothesis.
