FYI, the Praized team is attending Web 2.0 Expo and we have created a special blog called Web2Places (http://web2places.com/). Powered by our local search platform for blogs, it shows all "places/merchants" related to the Expo (the nearest coffee places, hotels, restaurants, where the parties are happening, etc.). You can vote and comments on any places in San Francisco to add them to the showcased list. Would love to get people's feedback on the site.
