You're right you wont get rich in these micro games,but you can make your beer money rather easily if you stick to quality openers.I have very limited time to play so I have to hit and run.I rarely play more than an hour per session.After an initial loss playing loose and aggressive I tightened up and now average 5 bb's per hour.Keep in mind I play short sessions and have lost my buy in to "Bingo Players" drawing out a couple of times and I don't usually rebuy.You would do well to profile players and pick the tables where you know the weak ones are playing.I don't know how well I would do if I played longer sessions but I belive if you play tight and aggressive you could do rather well.
