This is an interesting thread. I find Chatroom netiquette and courtesy challenging to get right all the time. Sometimes a person comes in during the middle of a conversation -- it can be challenging to get the new person up to speed.

The newcomer may have his/her own conversation needs that don't fit in with the current thread. It's easy if one person is in near-crisis to decide who gets my attention, but less easy if both conversations are equally compelling.

Lastly, there are instances where two people want to talk about one thing, another two about something else. So there's lots of confusing cross-talk going on.

I do the best I can to be polite to everyone -- including the person I already was talking with when we are not finished -- but I may have offended people.

I am probably going to offend someone by saying this, but I think that a person who enters the room, and expects a conversation to end and now focus on him/her, might try developing a bit of patience. If people do not offer to recap the current conversation for you, monitor what's going for a few minutes. Ask for a recap if you can't figure it out.

If you have a pressing need to share about something -- tell people what it is, instead of attacking them for continuing a conversation.

If these thoughts go against popular netiquette, I am open to being set straight.
