> 1) you think that people interested in reading about Airbnb are behaving irrationallyEvery angry mob is irrational, even if there is a perfectly rational reason for their anger.
While concern about what has happened, is happening, should be happening (in various peoples opinions), and so forth is definitely rational as is an interest in watching it all play out (even if you don't care for airbnb at all specifically, this could possibly have implications elsewhere too).
People posting the same thing that others have already posted (or something so similar it makes no difference) and other people voting everything up whether it is a duplicate or not is irrational. It bends the system here potentially making the site less useful/interesting to others, it isn't going to change the situation, and the confusion of partial discussions spread over threads is going to put people off that might have otherwise cared about the situation (they'll stop reading any post about it, no matter how high up pages 1 it is, as they'll start to assume it is the same as last time).
lt;dr: the interest/concern is not irrational but some of the behaviour seeming steming from that is, so suggesting some people are behaving irrationally is not incorrect (IMO).
