I also take mine out as I go - I am not a real fast sewer but sometimes I do forget and sew over them. Sometimes it works and sometimes broken needles and bent pins.

I pin a ways in from my 1/4" seam and don't take the pins out until I am finished, don't really sew over them but by them.

No, I take em out as I near them.

I take them out.. my machine is worth more than the itty bitty split second it would take me to remove the needle that could cause enormous damage to it - why pay a repair man when i could very well use THAT money to buy more fabric..

It really isn't wise to sew over pins as it eventually wears out the feed dogs on your machine.

I do my best to never sew overf pins, as I could damage the needle, and I hate having to put in a new needle because then I'd have to rethread the machine - not fun. I try to pin far enough back so that I don't have to take the pins out, but if not, I take them out before I get to them.

I have a Viking computerized and when I got it the dealer told me NEVER to sew over pins with my machine. So I never do. I usually put the pins in horizontally just so the presser foot misses them. If I'm matching seams, I put them in vertically and sew right up to them and then remove before going over them.
