Find something interesting and post a link to it and briefly describe why it's interesting. Your base move is a news article. But, I am more than happy to accept anything that's just novel, and related to information systems/technology as long as you can justify it. This might be a news article, it might be an opinion piece, it might be a trending twitter thing, it might be a non-IT related issue that you can point out how IT relates to it, etc. But you're trying to show that you're staying on top of current business news, with respect to technology and systems.
