Unique Identification Authority of India chief and Infosys co-founder Nandan Nilekani joined Twitter the day after news broke that he could be contesting elections from South Karnataka - his bastion. He is playing it safe on Twitter by not following anyone yet and by tweeting sparingly. The number of his followers has doubled from 650 plus on Wednesday to 1,300 on Thursday evening. A majority of Nilekani's current followers seem to be techies, journalists and some John Does; no political big-wigs are on the list yet. If one is looking for signals as to which way the wind is blowing then the latest tweet from him came on the occasion of Gandhi Jayanti!
