I like this from Cristina Costa who uses Skype in much the same way as I do: “We could create a skype chat log ( this is a feature quite unknown by skype users, but this has become the main communication channel of a group of webcasters I belong to, and it is incredible how the chat has grown and how we have bonded together. Apart from our blogs we keep this skype written chat open and include new people every time someone asks to join us. It is basically an ongoing IM conversation – every time someone has a question, an idea, etc they just type something in that chat log and the others will automatically receive it when they come online. In other words, what it allows us is to engage in a mix of real time and asynchronous communication).”
