I guess what I'm asking is, at it's core, it's just gossip, but at what point does it cross the line? Where is that line? Because it's easy to say any gossip is crossing the line, but then complaining about a bad driver is exactly that: gossip about an anonymous party. Those "OH" tweets become just as bad. Which is why I ask: where do we draw that line?
