You can totally bluff at low stakes. What I have come to realise is that, among the completely clueless, there are a number of people (I count myself among them) who are flawed but have some kind of handle on the game. They read these forums, they read sklansky and brunson, they have their odds tables and hand rankings by their side. They're still learning, they get over-confident scared often, they tighten up like a clam when things are going badly, but they're not entirely hopeless.

And it's these people you have to play at $25NL. The fish, it's taken as read that you'll milk them (if I may mix metaphors for a moment). But the moderate players at the table (as few as, um, none but as many as 5 or 6 players at certain times) do play "properly" *to the best of their abilities*. And this is where superior knowledge and tactics works best, and this includes bluffing.
