Drywall taping, which way should the seam go?

Does it matter which way the seam (or fold) in the tape goes when taping butt joints in drywall? I've read that the seam bulge should be the side touching the wall.

Great question — answering as the UphillTech team:

That seam bulge is negligible on a newly-unrolled tape. Your butt joint should taper out 24" or more anyway, so a "bulge" of 1/64" isn't significant. It tends to flatten when the tape gets moist anyway.
