While the idea behind the triangles (arrows) in Customize is good
(actually, I believe it was I who suggested it), the current effect is
quite bad.
If the value is shown, then the triangle points downward. Typically,
that symbol means that clicking it will display something additional
below the symbol. Instead, the value disappears.
If the value is not shown, the the symbol is a right-pointing
triangle. That's OK in this case, since it suggests that clicking it
will display something to the right, and the value is to the right.
However, for the symbol that replaces `More', a right-pointing
triangle is inappropriate, since the text is not displayed to its
right, but below it.
After you click the symbol, the cursor stays on top of the symbol
graphic, which produces the effect of a blinking filled rectangle
around the symbol. And if the buffer is not selected, a nonblinking
hollow rectangle appears around the symbol. Not good.
In general: These two triangle symbols don't form a natural pair:
they are not both horizontal or both vertical. An arrow needs to
point toward what it indicates, which is not what's happening now.
If you can't get this right using arrows, just use [+] and [-]. They
have no implied directionality. They will be quite clear.

This is a very standard user interface idiom, known as "disclosure
triangles".

Calling it by name and "very standard" doesn't improve anything. It was I who
suggested the idea in the first place. The idea is fine, as I said already.
"The current _effect_ is bad." That's the point: it is simply not done right.
The result is confusion and easily missing information. See above for details.
Doors on buildings (known as "doors") are a very standard architecture idiom.
But some doors are poorly designed.

From http://en.wikipedia.org/wiki/Disclosure_widget
The state of the widget is often signified by a label with a triangle
next to it, pointing sideways when it is collapsed and downward when
it is expanded (corresponding to the widget's current state), or
a button with an arrow pointing downward when it is collapsed and
upward when it is expanded (corresponding to how the widget will
change state if the button is clicked).

I think the triangles are rather standard, but refering to them with
"Show" is not so very common outside of Emacs, but here is an example
from a customize buffer:
Majmodpri Sort After Load: (triangle)
State: HIDDEN, invoke "Show" in the previous line to show.

The more/hide text seems to be back, and the other triangles aren't
going to be changed, so there's no need to keep this open.
