Social Networking Sites have evolved to a great extent and are a good source of information which can help in personalizing the web experience. With the recent spat between Facebook and Google it was quite evident that Google will have its own way and the Google+ indeed seems to be an apt answer to Facebook. Google started the project step by step with Google Wave, Google Buzz and now its in penultimate stage.

Google Plus, Google's latest attempt at a social networking service, has launched in similar invite-only form. But instead of getting on the list at an exclusive club, a Google Plus invite is more like an opportunity to sign up for a slightly unsavory psychological experiment. Plenty of people are begging for Google Plus invites on Twitter, but people on Twitter would beg for a bullet in the foot if the bullet was made by Google.
