How many do you vote for?

Hey folks! I'm hooked to Saregamapa! I was wondering how you decide to cast your vote! I make it a point to vote for everyone who deserves to be in the next round and leave out just the few who did not impress me at all. This is my way of ensuring I do my bit to ensure the contestants who are good but not great, stay on as long as they deserve to.. Do you do the same? OR do you just vote for the Aneeks, the Rajas & the Amanats alone? I think you should vote for all who deserve to make it to the next round. After all when you spend time in the forum, just go to internet voting & vote for all who did well! It just costs your time!
