Loosenes has nothing to do with agressiveness. You can play loose, just seeing a lot of flops, which is in my opinion very good strategy at small stakes because you have great implied odds if you hit. But don't bluff this stakes! In tighter games, I think that you should be more prepared to steal, but fold more often against a raise if you get something like suited connector. In tight games, people will punish you and you won't get implied odds to continue with drawing and they won't pay you off when you hit, but at micro levels, people will usually give you the right odds or at least implied odds to draw so you can take a lot of shots. My point is: you can play loose and make money or you can play tight and lose money. Just find your style and if you play loose, don't fall in love with your hand. (If you play A2s you are not looking for top pair, but flush).
