The veined octopus (Amphioctopus marginatus) uses coconut shell halves to build a shelter.

An octopus that uses coconut shells as portable armor is the latest addition to a growing list of animals that use tools.

The veined octopus (Amphioctopus marginatus) apparently can stack discarded coconut shell halves just as one might pile bowls, sits atop them, makes its eight arms rigid like stilts, and then moves the entire heap across the seafloor. These soft-bodied creatures perform this ungainly 'stilt walking' to use the hard shells for shelter later when needed."

Elizabeth Bernstein writes an article about Facebook. She and Matt Brown, Gwen Jewett, Alex Gilbert, James Hills, Kimberly Kaye, Heather White and a number of other people I'm not particularly interested in, share some concerns about communication standards on the web. Social communication standards, that is, not TCP/IP, HTTP and the like. They find they get to know just a little bit too much detail about their 'friends' lives, and point out how people can 'miss behave' on facebook. I wasn't aware that that is very particular to social websites. Apparently they rather have their friends hide much of their personal lives, interests and likes, and are not so keen on knowing what their friends think of things. They languish for the rules of social engagement of the past century. Well, in the new rules they are welcome to. Everybody has their own tastes, and if you don't like knowing about me, good for you! It's called Social 2.0, and there's plenty of room, also for you guys!
