The rake per player is much higher. The cardrooms are making a KILLING on these games.

You have to play more pots with a smaller edge.
These pots are activly contested either via the silly calls or mis-placed aggression. A lot of steal situations in online small stakes full ring end on earlier streets (granted my opponents are often giving up too easily.)
You must showdown more often with weaker holdings that you otherwise would dump in a full ring game because your opponents are more erratic and as a defensive measure.

Table selection is key, because if our opponents weren't so god-aweful-omfg-horrible these games would be very difficult to beat.

Getting dinged for $1, $1.5, $2 on almost every pot is far more expensive than getting hit up for $3 in out-of-control schooling pots.
