who decided what Neptune means?

Mostly out ignorance of traditional astrology gave the outer planets a lot of its significations. 
Uranus is said to signify inventions like the internet, but really inventions and systems of communication are significations of Mercury. It'd be the same with Neptune and Pluto. A lot of Neptune's significations come from Saturn, which just places less importance on Saturn these days, sadly. Interestingly however, the chart for when they discovered Neptune had Saturn and Neptune conjunct each other exactly, to the same degree. Check pic rel.

Not to say that they don't have meaning, they do, but in my opinion Modern astrology has over-exaggerated their importance. You have all you need with the 7 traditional planets.
I stopped using the outer planets and my astrology skills have improved so much as a result.
