People flat call too much. It is like limping and is passive play. In live tournaments, you will see a string of limpers or a string of flat callers.

Now in an ante game, if someone miniraises my BB, I am usually calling.

There are clearly times when flat calling is the best play, but there is nothing wrong with experimenting with always coming into the pot for a raise, particularly if it gets you out of calling or limping behind too much to see a flop.
