Some conditioners can lightly lather with water plus agitation, it's the cationic surfactants AFAIK
. It's not like mega bubbly like shampoo, but the conditioner stops feeling so slimy and feels like a soft foam, more like hair mousse or edible cream in a pressurised can. Put some conditioner in a small bottle add some water and shake, if you don't get a lather then a product is never going to on your head.
Really good information in the stickies on the Newbies board and the general haircare board about starting CG, should be hair properties and dew points covered. Also check out the main NC site, there are tons of articles covering everything hair related. The ones by 'curl chemist' Tonya McKay are particularly good. Maybe also read your book again, it is a lot to take in to begin with.
