IPhone, the same thing happens to me. I can't tell if my response was received and just has not shown up yet or did it not go threw at all. So I retype it and send it again, then look stupid.

The lag allows for conversations to continue and once your response appears it is no longer relevant. It makes it very difficult to tell which part of a conversation you are responding to as well. Multiple conversations are taking place and the lag just makes it hard to tell what is what.

I only come here now because this is where all my friends are and it feels like family to me and I do not want to lose touch with my friends. But it appears that people are leaving because of the chat. I know I have. I can go weeks now with out using this chat and checking to see how everyone is.
