I am developing a website and i need to know learn the location of visiting user(PC and mobile), i.e the user city.
Also tell me preferable technology and framework for developing a fast dynamic website like Digg. Actually, as far as my understanding goes, the asp.net websites are a bit slower than PHP/Javascript. May be i am wrong, but visiting Microsoft's website, seem to give this impression.
Thanks All !!
You could use HTML 5's geoLocation API, or use the user's IP address and try to find it's location - Google offers such a service
