One of the reasons for raising is to get money in the pot. I would argue that to raise when you think you have the best hand, depends upon your position at the table. If in early, if you raise too nuch you'll drive other player out. A call will keep them in, and you can raise later. In late position you can raise straight away, if other players have called. Conversely, a weakish hand is better raised early to try and drive players out. Middle position is a suck it and see situation, depending on your cards and who called before you.
