how tight do you actually play? do you have any way of finding out a %? In general, you should be playing maybe 15% of your hands or so, not including the blinds, so you should be playing 15% of hands where you have to put money into the pot to play, + whatever % you can just check in the big blind.

to an extent, people will know what you have more easily, but this isn't a problem. find the bad players and be patient and you will get paid anyway.
