I just don't have the patience for glue. The tape works way faster, and as Rob and others have pointed out, the feathers wear out before the tape lets go as long as your shaft was clean when you applied it.
I wipe down the shaft with denatured alcohol (not rubbing alcohol). You can by denatured alcohol at the big box building suppliers in quart cans. I've had my last quart for about two years and have at least half of it left.
After you wipe down the shaft it is critical that you DON'T TOUCH IT WITH YOUR FINGERS! The oil from your skin is what keeps the feathers from sticking. NOTE: this is true with glue as well.
For a while I was wiping down the quill too, but I've found that to be unnecessary.
I do add a drop of Duco or Fletchtite to the ends, depending on the shaft material. I'm not sure it is necessary to lock the feathers down, but I like overkill. The drop on the front of the feather also keeps the sometimes sharp ended quills from slicing your finger if you crowd the shelf like me. I don't quite shoot off my knuckle, but darn close.
