there is a serious challenge coming from India  for Facebook, Twitter,Google Plus and LinkedIn.Vebbler is based on crowd-layering model. Here, when you add a person, you have to put him or her into a group like workmate, acquaintance etc. One application of the model is in chat. When you are on holiday, you don’t want to chat with colleagues, but only with friends and relatives, you can disable them. Vebbler seems to be catching on: it has 45,000 users from 694 cities in 70 countries.

Vebbler may catch up with next generation who are in their teens as more ads are coming on facebook,twitter,google plus which consume more time in loading. Linkedin is different as it is a professional networking group.
