People will timewaste via email too, well in my opinion anyway - unless it's just naiivety at play (which I think some of it is too). Things like pingponging questions, asking in more and more depth exactly what you will do expecting you to sit at the pc all afternoon answering immediately - can you have sex on the bed, when can he undress you, how will he get undressed, can he have oral first, what will happen after that, and after that, can he go down on your before undressing, can you send some more pictures, or some of a particular body part. I'm not entirely sure what the end user gets from it, but it's pretty boring and unnecessary if it's done out of sheer nervousness (which sometimes it can be but most ladies would have switched off by then), but I also have a feeling someone is often sat there having a laugh too.
I like email because it means I can answer when I have chance, and that the phone isn't constantly ringing with calls (which is nice but not very practical). Only issue I have is that folks will email with short notice enquiries, which unless you happen to be right at the pc, or able to type several emails back and forth generally isn't great for getting something arranged in a quick, easy, simple and relaxed manner. And with all the goodwill in the world, IBlackberries and Iphones do not always receive email instantly. Instead you are both hovering over the keyboard for twenty minutes, bashing out the details when a 2 minute conversation would get the ball rolling, and everyone on their way to a sweet meeting.
So that's my take on email!
