I leave my MacBook Pro plugged in to its wall adapter essentially all the time, even after the battery is fully charged. Is this a bad thing to do? I don't want to ruin the battery. But I don't like to let it run down while I'm using it either.
Thanks!

No, it's not. The AC adapter knows not to overcharge it.
Don't leave it plugged in all the time. You WILL ruin the battery that way. When it's fully charged, unplug it and use it until it needs to be charged again.
My original 2002 TiBook battery with 600-odd charge cycles still gives me 2-2.5 hours use and over the last 5 years I've regularly used it plugged in.
When it's plugged in it's not drawing on the battery and hence is not using charge cycles. Batteries have a finite number of cycles before they start to degrade. However you do need to entirely discharge batteries regularly to keep the electrons flowing. So you can happily us it plugged in but now and again use the battery.
You mustn't overcharge a Lithum battery or it may explode but like Chucker says the charger knows when to stop.

I think I recall reading somewhere that an iPod can be charged all the time and a not be affected. I wouldn't know if that goes for MacBooks too. Seems to me it would...
Ok...half of you say no and half say yes.

My cell phone battery manual and or website says in one place it's OK to leave the charger plugged in. You won't hurt the battery. In another place it says to never leave the battery charger plugged in after the battery is charged or you will ruin the battery. SOS
