Twitter sometimes feels like eavesdropping. As in, I can read other people's entire conversations and not know whether or not it's okay to jump in. Seriously, what is the etiquette with butting into other people's online conversations (if I have something relevant to say, of course)? Are new people people welcome, or do you see it as some sort of intrusion?
Personally, I wouldn't mind if someone jumped into my twitter conversation. If I wanted to keep it private, I would use a means of communication that wasn't twitter. But I'm usually more open-minded about having conversations with random strangers, whereas others might think "who are you and why are you talking to me."
What's everyone else's take on this?
