This list really lacks detail.  There are myriad other hybrid methods used that are not aero or hydro but are soil-less.  There are soil-less grows that happen in pots just like dirt grows but rely entirely on hydro nutrients to feed the plants which are not considered hydro but definately not considered 100% orgainic but more appropriately called "soil-less" grows and can be very effective.

speaking of efficacy, this list would be far more effective and have a much greater education potential if it included 1)Brand Name or Trade name devices (hydrofarm buckets, Aero garden, Jet-gro etc... or  Ebb/Flo, Drip feed, Deep-water culture, NFT etc...) because even though many methods fit under the umbrella term "hydroponics" they are in fact very different.
