what u got2 understand is that online-poker is getting much harder to beat, as time goes by. I've noticed over the last 6 months(300,000 hands) my win rate has decreased and I've improved quite a bit in that time. Its all the new books and information about.
In 5 years from now low limit poker will be domminated by chinese and indians grinding it out for $5 a day (which will be good money for them)
Best to stick to home games.
Good luck
