There's just over a month left until DrupalCon Chicago. I've been going over the final session list and I'm jazzed. Looks like some great sessions this year. Now I just need to figure out human cloning so I can attend all the sessions I want.
This year's conference page also has a neat feature on the Schedule page: Each session has a button next to it to add it to your schedule (or remove it, if it's already on your schedule). You can then view your customized schedule through a tab on your account page. I haven't seen anything about how they implemented it, but my guess is that it relies on Node Queue. The only thing I'd change about what they've implemented would be to add a print-friendly version of the My Schedule list and maybe a means to export it in iCal or other calendar format.
