The Market makers job is to set the bid and ask at the price level that will create the most volume. MM's make money on volume and number of trades. Traders here are being patient and are trying to place buy orders at the bid rather than the ask. Solid support on the bid with several MM's lined up on the bid is a healthy thing.
Just remember one thing though if news of a merger suddenly hits those same traders trying to buy at the bid will be the first ones to chase this right up the price ladder. That's one way to get a dramatic price move.
