As many of us around the Planet, I do prefer using emails and IM rather than plain old telephone for business. Electronics communications allow me to keep track of the discussions, archive threads, etc.
For instance, I like to use Skype for interviews : the 'View Chat History' feature is a great tool for reviewing the records. Emails : since the NeXT Cube (I bought one, back in 1993) and its wonderful Mail app, which is the ancestor of the current Mac' Mail app, I use my email client as a datawarehouse. I keep history of my different jobs in there, together with key files such as presentations, I send draft ideas and memos and to-dos to myself, etc. By the way, I'm not the only one to use Mail this way : have a look at this guy here (hint : it's about a Leopard).
Also, electronics means less paper, which is quite a nice trick for someone who wants to save the Planet (not Superman, me ;-) to help saving the Planet.
Anne Zelenka of WebWorkerDaily has recently posted three articles which summarize the ' style & etiquette ' of the modern communication tools. It's so true. And fun ! Enjoy reading " How to Annoy People Using Instant Messaging ", " 27 Tips for Teleconferencing ", and " How to Screw Up An Email Negotiation " as much I did.
