I've started reading DC three months ago and i feel I've improved lot of my vocabulary by doing so.
Lot of my Friends told me that reading HINDU brings in more richness in your than DC to do.
What i personally feel is HINDU all deals with the politics and the exhaustive things which actually we youngsters don't need ver as DC goes with the peppy interesting things dat a metro guy to deal wit.
Of course i do agree that HINDU da classic is having much more vocabulary but actually is that much vocabulary needed to us at this stage.
so I'm going with DC which i feel pretty comfortable with.
