I'm not astonished or amazed that you are astonished at that, you
have
always been that mindlessly obsessive about words.
Daft in the first place to say "drywall", as all walls are dry,
unless made of mud, which is still dry once it's set.

Plastered walls are wet when you are doing the plastering, stupid.

Not usually in America, where they just tape and fill the joints.
Hence
"Drywall".
wonder what they call Ames tape ?

I assume that's a company name, like Duck Tape.* There must be a generic
name for it.

Anyway, isn't that the cheating way of filling gaps?

Nope, it's the only sensible way to do it.

Skimming?

Skimming is to make a flat surface from a rough one. Plasterboard is
already flat. You only need to skim the joints once you have applied the
tape.

Kinda like sellotaping things together instead of using screws!

Nothing like. The tape doesn't hold it to the wall, stupid.

I didn't say it did.* But it can come off.

Not once the joint has been skimmed. BTW, have you ever seen the
jointing tape? Hint, run along to the local hardware and take a look at
some. That will inform you so preventing some of these ridiculous
comments coming from your direction.

Isn't that tape going to peel off at some later stage?

Nope.

Why not?* Is it magical?* Every other tape comes off.

Another ridiculous comment. See my hint above. After skimming, the tape
becomes an integral part of the wall.
"Drywall tape" is only tape in that it is a narrow strip. The real
stuff has NO adhesive. There is fiberglass tape that has a bit of
sticky to it to hold it to the wall untill you get the mud on - for
DIYers. The real stuff gets trowelled into a thin coat of "mud" and
then gets "bedded" in with a covering coat. A real good job gets
bedded in "setting compound" which is trowelled slighly shy of the
surface - almost filling the recess of the edge and is "sponged" so
there is no compound on the surface - it is then "skimmed" with the
lightweight filler. Setting compound is hard in 30, 45, or 90 minutes
depending on the variety (durabond 30, 40, 45, 90 etc) and can be skim
coated quickly. Using lightweight compound for everything requires
anywhere from 8 to 36 hours to harfen depending on thickness,
temperature, and humidity so the job is a 2 day job, minimum. With
setting compound a good jointer can have a wall paint ready in about
10 hours. I've seen boarders install the drywall in the afternoon,
tapers and mudders work the night shift, and the painters come in at
noon and do the finish painting before supper time. A really GOOD
mudder barely has to sand the joints - he just gives the joint a light
rub with a damp sponge after trowelling and it's good to go if the
wall is being sprayed - the spray texture blends everything in. A
brush and roller job requires a bit more work but commercial and
institutional, as well as a LOT of residential is all done with
airless sprayers that leave a consistent fine texture.
