i've been limping here as well for awhile and i think i like it. a couple things about low stakes...

1- more fish.
2-fish take bad hands (TPWK or even less) too far post-flop.
3-fish slowplay too much.

i'm fine limping these hands because if i'm gonna raise them pre-flop i have to raise pretty heavily and that can easily turn into a bloated pot early leaving me with a pretty expensive c-bet, if i even do c-bet the flop, especially if i get more than 1 caller. if i raise medium-sized then i have a bloated pot vs. many opponents. if i just limp then i have a smaller pot to work with vs. people who slowplay too often and take bad hands too far. i don't mind that situation.
