I meant that when you are in a chat, (like on skype, or FB etc), then it goes really fast. People type small sentences and send them, some times even breaking a bigger sentence and send it in parts. And then it gets "confusing". Also not everybody writes a lot (you can see it right now on skype). It's easier to quote here, and to read what the people said in peace, without the screen jumping higher and higher in front of your eyes all the time
It has the disantvantage that it's slow, okay. But I think that when we are so many people together, then slow is better than fast. That's what I meant, I hope it's more clear now.
Disclaimer: I do find it fun wherever it happens! That's not a complain, I'm not a man.
