Whrrl.com - Twitterlike Mapping, Mobile Location Site

Whrrl is a fresh, new social network based on place discovery. Users can amass info whilst visiting real world locales via their mobile phones. Think Yelp or Yellowbot, with a mix of Jaiku on Google Maps. You can use Whrrl to find cool new places to dine, exotic art museums, cafes, bookstores, etc, based on your location. Searches can be further filtered by price range, activities, ratings, users, and distance among others. Reviews are written in a wiki format and incorporated in the Whrrl catalog for other users to consult. Each review can be spruced up with photos, ratings, and comments. To keep up with what everyone else is doing and reviewing, subscribe to the newsfeed. If you'd like things to remain amongst friends, simply stay within your trusted network or branch out to find out what other Whrrlers are doing. Whrrl also includes options for planning meetings and events with invitations and alerts. It's free to register with the service, and soon you may receive coupon tie-ins as the site expands its partnerships with popular brands.

"Social discovery for the real world.
Your friends and the places and events they "touch" light up so you can pick what's interesting to you. You control your privacy to share what you want with only the people you select.
Install Whrrl on your compatible mobile phone or use SMS text messaging. Either way, you get to Whrrl on-the-go."

The promotional tie-ins will insure that the network gets users and it guarantees revenue for Whrrl. In that sense, the site has a solid founding and while their idea isn't new, it seems to be well executed. Friends can easily keep in touch and find out all about latest and most happening events/places.

Will people be up for yet another mobile/mapping/Twitter mashup? What about privacy? Who can see your whereabouts and doings?
