In my experience bluffing further than c-betting is pretty pointless in low stakes games. I mean when your getting called all in with middle pair, why bother? Further on a sight like PP it seems that its also completely unneccary. Most of these guys seem to be completely oblivious to even some one who is set mining. I mean if I'm doing nothing for 50 hands and all the sudden I'm reraising you, why are you pushing me with TPMK?
