(Apologies in advance for the shameless plug.) It’s possibly a little late to talk about new year’s resolutions, but if anyone is a Facebook user and has given up smoking (or plans to), you might be interested in Quitclock.

My brother Alastair is a health editor for the Bupa private health insurance company, and thought of this neat project which was implemented by my housemate Martin Kleppman, and announced at new year. It helps you keep track of how long since you’ve smoked, how much money you’ve saved, lets you and your friends know how you’re doing, and has health tips about the improvements that you can expect from your new-found abstinence. I’m not a smoker but hopefully someone will find it useful.
