Thank you very much sir for sharing your view here. And i do agree that all mentioned website are quit demanded by the net users, but none of these can compete what Google is. Really I think the demand of the Google is increasing day by day as it associating the number of apps and the stuff which are very useful for the net users. I just say There is no comparison of mighty Google. It is the name which has made our life lighter, faster and smarter.
