I have been tending to move around playing online NL after about 50 hands so that nobody can get a read on me at a table. So far it has been paying off. The only problem is that I spend part of the time getting to know the other players.

Do you stick at one table for the duration of your play or do you move around a little? Would you rather "run the table" with an aggressive style or sit back and wait for the good cards to pop up?
