Some crews leave spoilers deployed if the runway and taxiways are wet or have ice or snow on them. It helps make sure your kite stays stuck to the ground and makes brakes more effective. It's a crew decision, and varies widely from crew to crew and with the conditions.

it is safer to taxi with flaps and spoilers deployed and retract them after taxi. The airline I worked for mandated this to be done once off the active runway. It is done for safety's sake, so as to not accidentally grab the wrong lever and retract the landing gear.

I never taxi with the spoilers out. In fact, I rarely use them out of the auto-spoiler function, so if you bring the power up as you're taxiing, they dump... as soon as you come back to idle, they pop back up. It makes a loud clunking sound as they stow and would probably annoy the passengers on a long taxi.

"Spoilers, Speed brakes, Zap flaps," all perform the same function...just at different stages of flight. They "spoil" the lift of the wing. On landing this helps to "stick" the plane to the ground, and act as a braking assistant. They have no affect on the A/C at taxi speed, so the crew just forgot to stow them, or were busy handling ground traffic etc...

They dump lift, so the aircraft stays on the ground once it's down and you can brake harder and are less likely to be disturbed by cross winds and such... more stable. They add a lot of drag too.
Why do they leave them up? Haven't got to that part of the checklist yet. Mostly I see them stowed soon after we taxi off the runway, if not sooner. Flaps up at that time too.

They might not have gotten to that part of the check list yet that calls for retraction of the spoilers as they sometimes get pretty busy up front.

In most cases they're left deployed? No, they're not. In most cases they're retracted after reversing course on the runway, or after clearing the runway.

For landing we use them to slow the plane down,but we never use them to taxi.

for better braking in the runway as it "spoils" lift, so the airplane has a better grip in the runway. not really helps for taxiing, maybe the pilot forgot the chacklist. ^^

helps keep the plane stable on the groung for the winds for other planes.
