Location is an important piece to solve the local search problem. Local search is all about location and asking the user again and again is certainly not the best thing from user perspective. After rolling out our location aware solution for mobile phones ( StreetSmart ), we bring the same service to web using some help from Firefox. Read more about Location Aware Browsing from Firefox at http://www.mozilla.com/en-US/firefox/geolocation/.
To use this you just need to have Firefox 3.5 and get started at http://www.asklaila.com/. We will use the firefox service to figure out your location and will provide you results around that area. The accuracy of our results depends on accuracy of location provided by Firefox.
Happy Location Aware Browsing!
