Some random stuff:
1. Facebook is cool, but I am finding a sticking point when it comes to my different 'faces' in public. What would be really cool would be being able to have a facebook to address my close friends, one to interact with the wider gaming community and one to interact with my students. As it is, the assumption that my interests are shared equally amongst all of my friends is annoying. Its like a living example of the old Geek Fallacies thing.
2. One of my students was astounded that I didn't have my profile on lockdown on Facebook? I was curious as to why I should do that. After all, the information there is for people to read isn't it? Oh, don't tell me - you write stuff on Facebook status updates that you don't want some people to read? Pretty silly putting it on the internet eh? I've learned my lesson.
3. Farmville. Could it be used as a teaching tool for simple resource management? There is very definitely a number of strategies that you can pursue depending on the time you have and the willingness you have to click squares continuously. I doubt it would ever get accepted but I reckon you could do something regarding costs and returns on investment!
