David Hopkins' blog, Don't Waste Your Time, is one of my favourite resource-sharing blogs. His posts are always detailed, thoughtful and balanced, and he provides great links. He tends to deal with themes rather than having one-off posts. His latest post, on Skype etiquette, contains a link to a great video which will strike a chord with anyone who has accidentally hit the enter button mid-message (watch below if you don't feel like clicking through to the blog itself).
The blog itself struck a chord with me because I haven't trained myself to ignore comfortably the skype ring, and I am occasionally ambushed online at an inappropriate time, such as during a training session, by a call from the other side of the world. And boy, are some people persistent! If only they'd get the message and hang up after 4 rings! My other issue with skype is to do with the webcam... we have it set up so that the kidlets can stay in touch with family and friends in South Africa, but I always find myself frantically checking what I (and the room behind me) look like before I hit answer!
