above is correct... plus when playing rags you have to teach yourself to ignore it when you make a pair, especially after you get called on the flop. You're happy, but you should generally assume you are still behind, just picked up some outs.

Another category of - what does a smallish bet like this mean - would be he flopped a monster, puts you on a hand (in this case, say he made a set and thinks you have an over pair) and assumes if he puts in a bet you're re raise to push him off. Classic Doyle - lead into the raiser when you make a hand.
