Wired does an update on Miss Manners. The list is pretty interesting. Some of them:

• Delete unwanted posts from your Facebook Wall. Yup. You need to have ownership of your own Wall.
• If you can’t find it online, feel free to Bit Torrent. Totally agree with this sentiment. Publishers/movie and recording studios should know that when people can’t find what they want legally, they will find it illegally. So stop fighting piracy and make your contents available everywhere.
• Don’t blog or tweet anything with more than half a million hits. I don’t necessarily agree with this. Information does not flow equally everywhere and something that is hugely popular to a certain crowd may not even be known to another crowd.
