Windows Live Local
This is cool.

But this is cooler...

Windows Live Local has some cool new features. You can now log in using your Microsoft passport and save "Collections" of push pins. I totally wanted this! In the first pic above, I have four push pins showing various points of interest for our upcoming wedding next month in Sedona. I had mapped these points before but wasn't able to save them - which drove me nuts! Now I can save them as a collection and I called this one, "Wedding".
The second picture is showing a Traffic view. Not all cities, understandably, show traffic, so I pulled up New York city because I figured it probably has some massively bad traffic this time of night. The little caution signs show various hazards like the one popped up in the picture. I can't wait til it shows around us so I could check it before going places.
You can share your collections if you like via e-mail, MSN Messenger, or Blogging (in Spaces). Once I've added some more info. to our wedding collection, I plan on sharing it with my Mom and Peter so everyone can see what's going on.
