There is one sad thing about the user accounts that are getting generated everyday and not used properly. I don't know if this can be solved or not.

I think there should be a mechanism to remove or reset a user account that has not been used for over 2 years or something. Someone claimed and created @bala user account but they never used it. While joining or even today if it was available I would have taken that instead of using this user account with numbers in it. 😛 User account is one of the biggest identity here to grow. Something that people can easily remember. Sorry for sharing my sad story. 😛
