It's the most popular poker room. Therefore, you will find a great variety of players. A number of dagerous sharks, but also lots of awesome fish. Your table selection possibilities are very big.
On microstakes you will always find 6-12 tables with a very high plrs/flop percentage, of more than 40 or at least more than 30. These are loose games you can enjoy, where you don't even need to play mega-solid poker to win.
The two more common player types are the ones who see a lot of flops yet almost always fold to a flop bet (so cbet them, and if they fight back don't think they're good enough to be "playing back after noticing what you're doing", they probably have something big this time, so don't pay them off), and the tighter players who on the other hand stack off very lightly after the flop (so "implied odds" becomes your favorite poker term, you can defeat them with basic set mining).
You must also identify and note the extreme "old school" calling station and maniac cases, as you will win big playing right against them, and also exploit the Short-Stacks Without Strategy, who are either suicidal enough to raise/push QJo from UTG or stupid enough to limp/call with low aces, suited connectors or small pocket pairs.
And more importantly, if you feel several players in the table are somehow outplaying you, look for easier tables inmediately, you'll find them for sure.
