cairina.moschata answers:

The molecules that allow glue to stick are held apart when wet. When dry, the molecules come together and form a bond

if you want superglue to stick faster, breathe on it like you were misting up a window - the moisture accelerates the process.

as for waiting until "both surfaces are tacky" i thought it was just to give the gluea chance to stick to the surface before you tried to stick it to something else! oh well!
