This week, the Going Out Guide got even more social. We added two new buttons -- Want to go and Been there -- on each our pages for individual restaurants, bars, movies and the like. Click them to save what you want to try or where you've been, and we'll save your lists for you so you can remember all these ideas. When you sign in with Facebook, you can share your plans on Facebook, too.

It's a surprisingly easy way to get your friends talking. Our own Lavanya Ramanathan clicked Been there for Hanoi House, and she quickly got three likes and a different friend later asked (in person) what she thought of the place.

Try it yourself: Find a place or event you want to go to (hint: there are lots of parties for this inauguration weekend), click Want to go and see how fast one of your friends says, "When should we go?"
