I agree that the available features can steer the online community culture and behaviors, but it's not determinative. I don't see why online communities should give up useful features just because other communities use them in a way you don't like.

I've been using mailing lists for about 30 years now. In the days before social networks, there was tons of forwarded crap and email chains, such that debunking them was a cottage industry. This behavior eventually moved to Facebook and Twitter which is perhaps why email lists seem more civilized these days, but I don't believe its the features that are driving it.
