I love Skobee

Skobee, a brand new online planning app, is now in Beta and I love it. It's super simple, but effective. You can post your plans and invite people to see the details—date, time, place (including map), and who is invited. In addition, anyone can leave comments. The best part is that you can make your events public or private. For public events, it's possible to see which events and places rank as the most popular. A nice way to discover new places and let friends keep track of your plans!
