While I don't claim to speak for all explorer's, or even the majority, I suspect that quite a number of people who are long term explorer's are drawn to it because of our personality type.
We're not anti-social, but we do enjoy the quiet solitude of the explorer profession and I'm sure most, if not all of us have people in our friends list, and sometimes just seeing someone else's icon on the map is enough to make us feel like we're not in the game alone and that there's someone there to chat with if the moment presents itself, even if we play an entire session without chatting at all it's often enough just to know that we
can.
I've had a computer since the Apple IIe days and chat has never been more than a minor means of communication for me as I prefer the slower paced long format of the forum (and UseNet before that). Personally for me in-game, I like to exchange a few pleasantries, have a little back and forth or crack a game related joke or two for a few minutes and then get back to exploring while hoping that I don't come off as rude, I do genuinely enjoy a short bit of chat, but it's not really
my thing.
I've always found real-time chat to be a rather awkward way to communicate (I'm old school

, I even disabled text messaging on my phone), and then there's the issue of whether you stay "in character" for those who like to role-play when they're in the game, which I guess should be sorted out early on when chatting with someone new.
Just my random thoughts on the subject.
